Description
3,5-Dimethylbenzoic acid, also known as dimethylbenzoic acid, is an organic compound with the chemical formula C9H10O2. It is a white to light yellow crystalline powder and is characterized by the presence of two methyl groups at positions 3 and 5 on the benzene ring. 3,5-Dimethylbenzoic acid is a type of dimethylbenzoic acid, which is a derivative of benzoic acid with two additional methyl groups.
Uses
Used in Microbial Culture Media:
3,5-Dimethylbenzoic acid is used as a carbon and energy supplement in the culture medium of Pseudomonas sp. This application is particularly relevant in the field of microbiology and biotechnology, where the growth and maintenance of specific bacterial strains are essential for research and industrial processes. By providing a source of carbon and energy, 3,5-dimethylbenzoic acid supports the growth and metabolic activities of Pseudomonas sp., allowing for more efficient and controlled cultivation of these bacteria.
Purification Methods
Distil the acid in steam, crystallise it from H2O (m 171.2-171.7o) or EtOH, and sublime it in vacuo.[Beilstein 9 H 536, 9 III 244, 9 IV 1806.]
Check Digit Verification of cas no
The CAS Registry Mumber 499-06-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 499-06:
(5*4)+(4*9)+(3*9)+(2*0)+(1*6)=89
89 % 10 = 9
So 499-06-9 is a valid CAS Registry Number.

Paragraph 0048-0122; 0241-0245; 0271-0272, (2020/05/01)
The invention discloses a green synthesis method of aromatic acid. Nickel-catalyzed carbonyl insertion is carried out on aryl iodine in the presence of formate, acid anhydride, a phosphine ligand andan organic solvent by using a nickel catalyst to obtain the aromatic acid. Efficient catalytic conversion is realized by utilizing the cheap nickel catalyst, the reaction conditions are mild, and theoperation is simple.

The transition-metal-catalyzed carboxylation of aryl and vinyl chlorides with CO2 is rarely studied, and has been achieved only with a Ni catalyst or combination of palladium and photoredox. In this work, the cobalt-catalyzed carboxylation of aryl and vinyl chlorides and bromides with CO2 has been developed. These transformations proceed under mild conditions and exhibit a broad substrate scope, affording the corresponding carboxylic acids in good to high yields.
