Phosphorous acid, diphenyl ester, also known as diphenyl phosphite, is an organophosphorus compound with the chemical formula (C6H5O)2P(O)H. It is a colorless, oily liquid that is soluble in organic solvents and has a mild, characteristic odor. Phosphorous acid, diphenyl ester is primarily used as a stabilizer for halogenated hydrocarbons, such as polyvinyl chloride (PVC), to prevent degradation caused by heat and light exposure. Additionally, it serves as a flame retardant, plasticizer, and antioxidant in various industrial applications. Diphenyl phosphite is also employed as a reagent in organic synthesis, particularly in the preparation of other organophosphorus compounds. Due to its potential health and environmental risks, it is essential to handle this chemical with proper safety measures.

102-10-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 102-10-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102-10:
(5*1)+(4*0)+(3*2)+(2*1)+(1*0)=13
13 % 10 = 3
So 102-10-3 is a valid CAS Registry Number.

ORGANOPHOSPHORUS CHEMISTRY. 2. THE REDUCTION OF QUINQUEVALENT PHOSPHORUS TO THE TRIVALENT STATE

Engel, Robert,Chakraborty, Subir

, p. 665 - 670 (2007/10/02)

Phosphoryl and phosphonyl chlorides are reduced conveniently to the monobasic acid forms of the corresponding phosphorous and phosphonous acids by the use of sodium borohydride dispersed in dioxane.

Phenolic ester synthetic resin stabilizers

-

, (2008/06/13)

New ortho-alkylhydroxybenzylpropanediol compounds of carboxylic acids, aldehydes, ketones, phosphites, phosphates, and phosphonates are disclosed. The propanediol compounds have in the molecule from one to four preferably from one to three ortho-alkylhydroxybenzylpropanediol units, each of which carries one to two ortho-alkylhydroxybenzyl groups, and are highly effective stabilizers for a variety of synthetic resins. Stabilizer compositions comprising a orthoalkylhydroxybenzylpropanediol compound and a known polymer stabilizer, as well as synthetic resins stabilized with such stabilizer compositions, are also disclosed.
