20769-85-1 Usage
Description
2-Bromoisobutyryl Bromide is a kind of bromide being useful in the chemical industry. It is used as an intermediate for the synthesis of pharmaceuticals, agrochemicals, dyes and other organic chemicals1. It can be used as atom transfer radical polymerization (ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide; to form an N-protected halodienamide which provided fourand five-membered lactams in the presence of copper (I) and a tertiary amine; in preparation of polycaprolactone macroinitiator via reaction with oligomeric caprolactone dio and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface2,3. As a initiator precursor, it can also be used for surface modification of Ethylene-vinyl alcohol (EVOH) copolymer films to grow surface-grafted poly-(acrylamide) chains.

Uses
Different sources of media describe the Uses of 20769-85-1 differently. You can refer to the following data:
1. 2-Bromoisobutyryl bromide is used to prepare N-protected halodienamide, which provides four- and five-membered lactams in the presence of copper(I) and a tertiary amine. Further, it is used as atom transfer radical polymerization(ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide. It is also used in preparation of polycaprolactone macroinitiators through reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface.
2. α-Bromoisobutyryl bromide has been used:as atom transfer radical polymerization (ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxideto form an N-protected halodienamide which provided four- and five-membered lactams in the presence of copper (I) and a tertiary aminein preparation of polycaprolactone macroinitiator via reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface
Check Digit Verification of cas no
The CAS Registry Mumber 20769-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,6 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20769-85:
(7*2)+(6*0)+(5*7)+(4*6)+(3*9)+(2*8)+(1*5)=121
121 % 10 = 1
So 20769-85-1 is a valid CAS Registry Number.
