(1-chloro-2,2-difluoro-ethyl)-benzene, also known as 1-(chloromethyl)-2,2-difluorobenzene, is an organic compound with the molecular formula C8H6ClF2. It is a colorless liquid with a molecular weight of 180.58 g/mol. This chemical is characterized by the presence of a benzene ring, a chloromethyl group (-CH2Cl), and two fluorine atoms attached to the same carbon atom in the ethyl group. It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is essential to handle (1-chloro-2,2-difluoro-ethyl)-benzene with care, following proper safety protocols to minimize potential health and environmental risks.

Check Digit Verification of cas no

The CAS Registry Mumber 345-62-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 345-62:
(5*3)+(4*4)+(3*5)+(2*6)+(1*2)=60
60 % 10 = 0
So 345-62-0 is a valid CAS Registry Number.

MECHANISMS OF FREE-RADICAL REACTIONS. XX. REACTIVITY IN THE FREE-RADICAL HALOGENATION REACTIONS OF ARYLFLUOROALKANES

Dneprovskii, A. S.,Eliseenkov, E. V.

, p. 711 - 719 (2007/10/02)

The free-radical chlorination and bromination of meta- and para-substituted benzyl fluorides and 1,1-difluoro-2-phenylethane and also the chlorination of 1-fluoro-2-arylethanes by phenylchloroiodonium chloride and the bromination of meta- and para-substituted benzyl bromides were studied by the method of competing reactions.In all cases a good correlation is observed between log krel and the Brown ?+ constants.In cases where change in the reactivity in the transition from one reaction series to another is due mainly to the polar effect of the substituent whilethe selectivity is measured in relation to the polar effect direct relationships are observed between the reactivity and the selectivity.
