158429-66-4 Usage

General Description

(2-Methyl-4-carboxyphenyl)boronic acid is a chemical compound that belongs to the class of organic compounds known as benzoic acids and derivatives. These are compounds containing a benzene ring which bears at least one carboxyl group. This particular compound is a boronic acid, characterized by the presence of a boron atom bonded to an oxygen atom and two separate carbon atoms. In the chemical industry, boronic acids play important roles in many organic reactions, including Suzuki coupling reactions which are extensively used in organic and medicinal chemistry. The presence of the carboxylic acid moiety in its molecular structure suggests it may have acidic properties, potentially making it useful as a pH adjuster in certain applications. However, information about its specific properties and uses is quite limited.

Check Digit Verification of cas no

The CAS Registry Mumber 158429-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,2 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158429-66:
(8*1)+(7*5)+(6*8)+(5*4)+(4*2)+(3*9)+(2*6)+(1*6)=164
164 % 10 = 4
So 158429-66-4 is a valid CAS Registry Number.

Fast and Tight Boronate Formation for Click Bioorthogonal Conjugation

Akgun, Burcin,Hall, Dennis G.

supporting information, p. 3909 - 3913 (2016/03/19)

A new click bioorthogonal reaction system was devised to enable the fast ligation (kON≈340 m-1 s-1) of conjugatable derivatives of a rigid cyclic diol (nopoldiol) and a carefully optimized boronic acid partner, 2-methyl-5-carboxymethylphenylboronic acid. Using NMR and fluorescence spectroscopy studies, the corresponding boronates were found to form reversibly within minutes at low micromolar concentration in water, providing submicromolar equilibrium constant (Keq≈105-106 m-1). Efficient protein conjugation under physiological conditions was demonstrated with model proteins thioredoxin and albumin, and characterized by mass spectrometry and gel electrophoresis.
