Which Phosphorus Compounds are Available?
At ChemPUR, you can obtain Phosphorus(V) oxide, also known as diphosphorus pentoxide or P₂O₅, in purities from 98+% and from 99%. The compound is available in 500g containers and is suitable for applications requiring a strong dehydrating or desiccating substance.
For example, you can use Phosphorus(V) oxide in chemical synthesis or analytics to bind moisture, dry reaction systems, or support dehydration reactions. This clearly distinguishes it from elemental red or black phosphorus, which are primarily relevant for synthesis, semiconductor, and material science applications. If you require a different phosphorus compound, a specific purity, or a different container size, please do not hesitate to contact us. We will evaluate the available options for your application.
For Which Applications is Phosphorus Used?
In research and development, phosphorus is primarily used where defined purity, controlled reactivity, and specific material properties are required. Depending on the modification and compound, phosphorus is suitable for very diverse applications – from chemical synthesis to material development.
Red phosphorus is used, among other things, as a starting material for phosphorus-containing compounds and in specialized synthesis processes. High-purity grades are particularly relevant when impurities can affect reaction control or subsequent material behavior. Black phosphorus is primarily of interest for modern materials research, for example, in studies on two-dimensional materials, electronic properties, or new energy storage concepts.
Phosphorus(V) oxide is frequently used as a strong drying and dehydrating agent in synthesis and analytics. Furthermore, phosphorus compounds play an important role in the development of functional materials, catalysts, specialty chemicals, and semiconductor-related applications. The appropriate phosphorus quality depends on purity, modification, reactivity, and the desired area of application. Our expert team will gladly assist you in selecting the suitable phosphorus product for your application.
Is Phosphorus Supplied Worldwide?
ChemPUR supplies research institutions, universities, laboratories, and industrial companies in numerous countries. Phosphorus and phosphorus compounds can also be delivered internationally, depending on the product, quantity, and destination country. Since certain phosphorus products may have special requirements for packaging, storage, and transport, we carefully review each inquiry. In doing so, we consider the applicable dangerous goods, export, and import regulations, as well as the necessary accompanying documents. This ensures safe and compliant processing of your order.
For you, this means clear communication, expert support, and a reliable assessment of delivery options. Whether small quantities for laboratory needs or larger quantities for research and development projects – our team will gladly clarify which options are available for your destination country. Simply contact us. We will individually review your inquiry and assist you with the appropriate shipping solution.
In Which Purities is Phosphorus Available?
Purity requirements vary significantly depending on the application – our product range accounts for this. Red phosphorus is available in purities from 99.995% up to 99.99999% (7N, Semiconductor Grade), with the highest grades specifically intended for the semiconductor industry. Black phosphorus is offered with a purity of 99.9+%. Phosphorus(V) oxide is available in two quality grades: from 98+% and with a minimum purity of 99%. The products are filled under protective gas – argon or inert gas – to prevent reactions with humidity and oxygen. Electronic-grade qualities are also available for applications in electronics and semiconductor technology. For questions regarding the suitable purity level for your project, our specialists are directly available to assist you.
Why is ChemPUR the Right Partner for Phosphorus?
With phosphorus, more than just the desired purity matters. Modification, packaging, documentation, availability, and secure handling are also crucial. ChemPUR supports you in selecting precisely the quality that suits your application – from synthesis and analytics to material science or semiconductor-related applications. Our phosphorus range extends from 99.9+% to high-purity qualities in semiconductor grade. This covers both classic laboratory applications and particularly demanding research and development projects. As an ISO 9001:2015 certified company, we operate according to defined quality standards and value traceable specifications.
Through our international dealer network, we can also evaluate special qualities, custom quantities, or project-specific requirements. As a family-run company, you benefit from short communication channels, personal advice, and direct communication with experienced specialists. This way, you receive not just a product, but a reliable solution for your phosphorus procurement. Contact us – we will jointly clarify which quality and delivery form are suitable for your application.
Which Forms of Phosphorus Does ChemPUR Offer?
ChemPUR offers phosphorus in several modifications and delivery forms. Black phosphorus is available as pieces with a size of < 4 mm and is particularly suitable for material science research applications where the specific properties of this modification are paramount.
Red phosphorus is offered as pieces in various qualities – including those filled under argon or inert gas. For particularly demanding applications, high-purity variants up to 7N quality in semiconductor grade are available. Depending on the version, pieces without a firmly defined fraction as well as defined size ranges such as 2–5 mm or 5–8 mm are available. The product range is supplemented by Phosphorus(V) oxide in purities from 98+%. This is not elemental phosphorus, but an important inorganic phosphorus compound used, among other things, as a drying and dehydrating agent.
The suitable form depends on the application: Black phosphorus is primarily relevant for modern materials research, red phosphorus for synthesis, semiconductor, and development applications. Phosphorus(V) oxide is used when a reactive phosphorus-oxygen compound is required. Our expert team will gladly assist you in selecting the appropriate quality and delivery form.
What Distinguishes Phosphorus from Other Elements?
Phosphorus is particularly interesting for research and development because it is available in different modifications with very diverse properties. This allows the element to be specifically selected for various applications – for example, for synthesis processes, semiconductor-related questions, or modern materials research. Red phosphorus is primarily relevant when an easily manageable, phosphorus-containing starting substance is needed for chemical syntheses or technical development processes. In high-purity qualities up to semiconductor grade, it is also suitable for applications where low impurities and reproducible material properties are crucial.
Black phosphorus differs significantly from this: its layered structure and semiconducting properties make it particularly interesting for material science investigations, for example, in the context of functional materials, electronic properties, or two-dimensional structures. For users, phosphorus thus offers a rare combination of chemical reactivity, structural diversity, and material-technical potential. The suitable modification and purity depend on the respective application area. ChemPUR will gladly assist you in selecting the appropriate phosphorus product for your application.
