Hypophosphoric acid tetrapropyl ester, also known as tetrapropyl hypophosphite, is a colorless liquid chemical compound with the molecular formula C12H29O4P. It is derived from hypophosphoric acid and is formed by the esterification of hypophosphoric acid with propanol. hypophosphoric acid tetrapropyl ester is widely used as a reducing agent in various chemical reactions, particularly in the synthesis of organophosphorus compounds and as a flame retardant in plastics and textiles. It is also employed as a stabilizer for chlorinated solvents and as an intermediate in the production of other phosphorus-containing compounds. Due to its reactivity and reducing properties, it is essential to handle hypophosphoric acid tetrapropyl ester with care, as it can be sensitive to air, moisture, and heat.

679-38-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 679-38-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 679-38:
(5*6)+(4*7)+(3*9)+(2*3)+(1*8)=99
99 % 10 = 9
So 679-38-9 is a valid CAS Registry Number.

Electrochemical Oxidation of Metal Dialkyl Phosphites and Their Reaction with Halogens

Romakhin,Zagumennov,Nikitin

, p. 1022 - 1026 (2007/10/03)

Electrochemical oxidation of sodium dialkyl phosphites with alkyl radicals of normal structure leads to formation of tetraalkyl pyrophosphites as the main products, while electrochemical oxidation of litium dialkyl phosphites and sodium salts with branched alkyl radicals yields tetraalkyl hypophosphates. The reaction of metal dialkyl phosphites with halogens leads to analogous results.
