50-38-4 Usage

Description

2,3,5,6-Tetramethylbenzoic acid (THMB), also known as Prehn's acid, is a type of organic compound that belongs to the class of chemicals known as benzoic acids and derivatives. These compounds contain a benzene ring that is substituted by a carboxyl group and any number of alkyl groups. Unlike many other benzoic acids, THMB is distinguishable by its unique chemical structure, featuring four methyl groups and a benzoic acid moiety. The addition of these four methyl groups to its molecular structure makes it more lipophilic (fat-liking) compared to its benzoic acid counterpart. This chemical compound exhibits a range of chemical behaviors due to its molecular structure.

Uses

Used in Industrial Syntheses:
2,3,5,6-Tetramethylbenzoic acid is used as an intermediate in industrial syntheses for its unique chemical structure and lipophilic properties. Its ability to interact with other compounds due to its molecular structure makes it a valuable component in the production of various chemical products.

Check Digit Verification of cas no

The CAS Registry Mumber 50-38-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50-38:
(4*5)+(3*0)+(2*3)+(1*8)=34
34 % 10 = 4
So 50-38-4 is a valid CAS Registry Number.

Carboxylation of C-H bonds using N -heterocyclic carbene gold(I) complexes

Boogaerts, Ine I. F.,Nolan, Steven P.

supporting information; experimental part, p. 8858 - 8859 (2010/08/21)

A highly efficient [(NHC)AuI]-based (NHC = N-heterocyclic carbene) catalytic system for the carboxylation of aromatic and heteroaromatic C-H bonds was developed. The significant base strength of the Au-OH species is at the origin of the activation process and permits the facile functionalization of C-H bonds without the use of other organometallic reagents.
