Chemical Properties
Bis(2,4-dichlorophenyl) chlorophosphate is White Solid
Uses
Bis(2,4-dichlorophenyl) chlorophosphate is a phosphate catalyst used in the direct conversion of alcohols to azides via activation. It also acts as a coupling agent in the synthesis of oligonucleotide phosphorodithioates.
Check Digit Verification of cas no
The CAS Registry Mumber 14254-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,5 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14254-41:
(7*1)+(6*4)+(5*2)+(4*5)+(3*4)+(2*4)+(1*1)=82
82 % 10 = 2
So 14254-41-2 is a valid CAS Registry Number.

A highly enantioselective synthesis of phosphate triesters
Nakayama, Kensaku,Thompson, Wayne J.
, p. 6936 - 6942 (2007/10/02)
A general methodology for the preparation of both enantiomers of a variety of trialkyl phosphates with enantiomeric excesses ranging from 87 to 92% is described. Bis(2,4-dichlorophenyl) phosphoramidates bearing a 2-substituted pyrrolidine moiety as the chiral auxiliary are prepared and examined for their stereoselectivity. Considerations based on both the absolute configuration of the product phosphates as well as the X-ray structural determination of one of the bis(2,4-dichlorophenyl) phosphoramidates suggest these substitutions occur with preponderant inversion of configuration at phosphorus.
