General Description
1-phenylvinyl phosphate, also known as phenyl vinyl phosphate, is an organophosphate compound with the chemical formula C8H9O4P. It is a colorless liquid with a fruity odor, commonly used as a flame retardant additive in the production of plastics, coatings, and textiles. It acts as a chemical intermediate in the synthesis of other phosphorus-containing compounds and is also used as a flame retardant in the manufacturing of acrylics, polyurethanes, and epoxy resins. However, 1-phenylvinyl phosphate is a potential irritant to the skin, eyes, and respiratory system and may have harmful effects on aquatic organisms, and its use and disposal must be carefully managed to minimize environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 76625-78-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,2 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76625-78:
(7*7)+(6*6)+(5*6)+(4*2)+(3*5)+(2*7)+(1*8)=160
160 % 10 = 0
So 76625-78-0 is a valid CAS Registry Number.

Enol Phosphates from the Action of Monomeric Metaphosphate Ion on Ketones
Calvo, Kim C.,Westheimer, F. H.
, p. 2827 - 2831 (2007/10/02)
Prior research from this laboratory had demonstrated that monomeric metaphosphate ion, generated by fragmentation from β-bromophosphonate dianions, reacts with acetophenone in the presence of excess base to give a modest yield of 1-phenylvinyl phosphate.This paper expands on that finding; it presents studies of the effects of concentration of reagents, of solvents, and of variation in amine structure (i.e., of the base) on the reaction.These studies lead to experimental conditions where the yield of the enol phosphate of acetophenone, based on the β-bromophosphonic acid used, exceeds 80percent.Several other ketones can be similarly converted to their enol phosphates, although in inferior yield.
