General Description
Bis(2,4-dichlorophenyl) carbonate, also known as bisphenol-A bis(dichlorophenyl) carbonate, is a chemical compound primarily used in the production of polycarbonate plastics. It is derived from bisphenol A and 2,4-dichlorophenol, both of which are considered potential endocrine disruptors. Bis(2,4-dichlorophenyl) carbonate is used as a precursor in the synthesis of polycarbonate polymers, which are commonly found in consumer products such as food and drink containers, medical devices, and electronic equipment. However, there have been concerns about the potential health effects of bis(2,4-dichlorophenyl) carbonate and its ability to leach into products, leading to regulatory scrutiny and efforts to find safer alternatives.
Check Digit Verification of cas no
The CAS Registry Mumber 26496-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,9 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26496-99:
(7*2)+(6*6)+(5*4)+(4*9)+(3*6)+(2*9)+(1*9)=151
151 % 10 = 1
So 26496-99-1 is a valid CAS Registry Number.

NOVEL CATALYSIS OF o-NITROPHENYL CARBONATES BY p-DIMETHYLAMINOPYRIDINE
Brunelle, Daniel J.
, p. 1739 - 1742 (2007/10/02)
Transesterification reactions of o-nitrophenyl carbonates have been found to be greatly facilitated by use of p-dialkylaminopyridines as catalysts.A 20-fold rate increase is observed using 0.01 eq. of p-dimethylaminopyridine in place of 2.00 eq. of triethylamine.Such rate enhancement is not observed with p-nitrophenyl carbonates: 2.00 eq. of Et3N causes reaction to occur 8.5 times faster than 0.01 eq. of DMAP.DMAP catalyzed reactions of o-nitrophenyl carbonate have been used to prepare aromatic carbonates at 0 deg C in high yields, and avoid the necessity of using 2 equiv. of base.
