It is a methyl ester derivative of 4-chloromethylthiophene-2-carboxylic acid and is commonly used in the pharmaceutical and agrochemical industries as an intermediate in the synthesis of various compounds. This chemical is a pale yellow liquid with a distinctive sulfur-like odor and is known for its versatile reactivity and potential biological activity. It is often used as a building block for the synthesis of new drugs and as a key starting material for the preparation of a wide range of functionalized heterocyclic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 34767-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,6 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34767-85:
(7*3)+(6*4)+(5*7)+(4*6)+(3*7)+(2*8)+(1*5)=146
146 % 10 = 6
So 34767-85-6 is a valid CAS Registry Number.

SIMPLE PREPARATION OF METHYL 4-CHLOROMETHYL- AND METHYL 5-CHLOROMETHYL-2-THIOPHENECARBOXYLATE
Kozmik, Vaclav,Palecek, Jaroslav
, p. 1483 - 1486 (2007/10/02)
Selective reduction of a mixture of methyl 4-chloromethyl-2-thiophenecarboxylate (I) and the 5-chloromethyl isomer II, prepared by chloromethylation of methyl 2-thiophenecarboxylate (III), gave pure 4-chloromethyl derivative I and 5-methyl-2-thiophenecarboxylate (V) which on treatment with sulfuryl chloride was converted into the 5-chloromethyl isomer II.
