14315-11-8 Usage

General Description

4-Methylbenzothiophene is a chemical compound with the molecular formula C9H8S. It is a heterocyclic aromatic hydrocarbon that consists of a benzene ring fused to a thiophene ring with a methyl group attached to the benzene ring. 4-METHYLBENZOTHIOPHENE is commonly used as a building block in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and materials. It is also known for its strong odor and is used as a fragrance agent in perfumes and other cosmetics. 4-Methylbenzothiophene has potential applications in the production of dyes, pesticides, and other industrial chemicals, making it a valuable chemical in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 14315-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,1 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14315-11:
(7*1)+(6*4)+(5*3)+(4*1)+(3*5)+(2*1)+(1*1)=68
68 % 10 = 8
So 14315-11-8 is a valid CAS Registry Number.

Example 16'(2), (2008/06/13)

An N-alkoxyalkyl-N,N-dialkylamine derivative represented by the following general formula [1]: wherein the ring D represents a 5- or 6-membered heterocyclic ring or hydrocarbon ring; R3 and R4, which are the same or different, represent an unsubstituted or substituted alkyl, cycloalkyl or aralkyl group; and R1, R2, R5, R6, R7, R8, m and n are as defined in the specification, or a salt thereof has an anti-hypoxic activity, a nerve-protecting activity and a nerve regeneration promoting activity and is useful for the treatment of neurodegenerative diseases.

ALKYLATION OF THIOPHENES AND PREPARATION OF BENZOTHIOPHENES USING MODIFIED MONTMORILLONITE CLAY CATALYSTS

Clark, Peter D.,Kirk, Andrew,Mesher, Shaun T.,Yee, James G.K.

, p. 441 - 444 (2007/10/02)

Regioselective benzylation of thiophene and benzothiophene using benzyl chloride and a ZnCl2-promoted montmorillonite catalysts is described.An improved process for the cyclization of (arylthio)acetaldehyde dialkyl acetals to benzothiophenes using the same catalyst is also documented.
