Overview

Phosphorus pentoxide is a deliquescent compound prepared by reacting phosphorus with air. It is a commonly used as dehydrating and condensing agent in organic synthesis.

Application

Dehydrating agent used for halogenation with tetrabutylammonium halides. Process for Producing Halogenated Heteroaryl Compounds Phosphorus pentachloride has been used for the vaccum distillation of 1-methyl-2-pyrrolidinone (NMP), which was employed as mobile phase in a chromatographic analysis. It may be used as one of the reaction components in the synthesis of dichlorine heptoxide (Cl 2 O 7 ) and transition-metal phosphides (Ni 2 P, Co 2 P and MoP). P 2 O 5 supported on alumina can be used for the solvent-free and microwave-assisted preparation of 1, 5-benzodiazepine analogs. P 2 O 5 /KX (X = Br, I) reagent system may be used for the transformation of alcohols into the corresponding alkyl iodides and bromides. Phosphorus pentoxide/methanesulfonic acid (PPMA) may be used as a condensing agent and solvent for the synthesis of: High molecular weight poly(benzoxazole)s via direct polycondensation of aromatic dicarboxylic acids containing phenyl ether structure with 3,3′-dihydroxybenzidine dihydrochloride. Aromatic poly(phenylene ether ether ketone)s via direct self-polycondensation of 4-(4′-phenoxyphenoxy)benzoic acids. 1,3-1 H -dibenzimidazole-benzene by the reaction of isophthalic acid with 1,2-diaminobenzene.

Frequently Asked Questions

What is the purity of this product?

This product is supplied at ≥99% purity (chemical assay). Lot-specific values are stated on the Certificate of Analysis.

What does Anhydrous Grade mean?

Anhydrous Grade indicates that the material has been processed and tested for moisture-sensitive chemistry. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

How should this product be stored?

Store at room temperature under argon. It is supplied under an argon blanket; reseal under inert gas after each use.

How is this product shipped?

This product is classified as dangerous goods and ships via FedEx DG Service. Ground and other economy services are not available, and delivery to some destinations or address types may be restricted.

What are the CAS number, molecular formula and molecular weight?

The CAS Number is 1314-56-3, the molecular formula is P2O5, and the molecular weight is 141.94 g/mol. InChIKey YWEUIGNSBFLMFL-UHFFFAOYSA-N.
