Description
2-Aminoisobutyric acid, also known as alpha-methylalanine or a-aminoisobutanoate, is a rare, non-protein amino acid and an end-product of pyrimidine metabolism. It belongs to the class of organic compounds known as alpha amino acids, where the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2-Aminoisobutyric acid is very hydrophobic, practically insoluble in water, and relatively neutral. It exists in all living organisms, from bacteria to humans, and has been detected in milk (cow), potentially serving as a biomarker for the consumption of these foods. 2-Aminoisobutyric acid is excreted in the urine of about 5% of healthy individuals, and high excretion is an autosomal recessive phenotype.
Uses
Used in Diagnostics:
2-Aminoisobutyric acid is used as a diagnostic tool for predicting type II diabetes. The level of alanine aminotransferases, which are regulated by the alanine cycle and include 2-methylalanine as a derivative, can be used to predict the likelihood of developing this condition.
Used in Bioassays:
Due to its non-metabolizable nature in most organisms, except for a few bacteria, 2-Aminoisobutyric acid is utilized in bioassays for various applications.
Used in Pharmaceutical Industry:
2-Aminoisobutyric acid is a non-protein amino acid found in some antibiotics, where it acts as a strong helix inducer in peptides, contributing to the development and effectiveness of these medications.
Used in Research and Development:
As a component of the alanine cycle and a derivative of alanine, 2-Aminoisobutyric acid plays a role in research and development related to amino acid metabolism, protein synthesis, and the understanding of various biological processes.
source
2-aminoisobutyric acid is a rare, non-protein amino acid and end-product of pyrimidine metabolism, excreted in urine and found in some antibiotics of fungal origin. With the exception of a few bacteria, it is non-metabolisable, and therefore used in bioassays. It derives from a propionic acid and an isobutyric acid.

Check Digit Verification of cas no
The CAS Registry Mumber 62-57-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62-57:
(4*6)+(3*2)+(2*5)+(1*7)=47
47 % 10 = 7
So 62-57-7 is a valid CAS Registry Number.

Preparation method of 2-methylalanine
-
Paragraph 0040-0042, (2021/07/28)
The invention specifically discloses a preparation method of 2-methylalanine, belonging to the technical field of organic synthesis. The method comprises the following steps: condensing 2,2-dimethoxypropane serving as a raw material with tert-butyl sulfinamide or tert-butyl carbamate to generate Schiff base, then carrying out nucleophilic addition on the Schiff base and sodium cyanide or potassium cyanide under the action of phase transfer catalysis and ammonium chloride, and then adding acid to hydrolyze cyano groups so as to obtain 2-methylalanine. According to the invention, the used raw materials are easily to obtain and low in price; process flow is simple and convenient; reaction conditions are mild; requirements on equipment are low; total yield is as high as 80-83%; and the purity of the prepared 2-methylalanine is more than 99.6%.
General Synthesis of Amino Acid Salts from Amino Alcohols and Basic Water Liberating H2

supporting information, p. 6143 - 6146 (2016/06/09)
An atom-economical and environmentally friendly method to transform amino alcohols to amino acid salts using just basic water, without the need of pre-protection or added oxidant, catalyzed by a ruthenium pincer complex, is developed. Water is the solvent, the source of the oxygen atom of the carboxylic acid group, and the actual oxidant, with liberation of dihydrogen. Many important and useful natural and unnatural amino acid salts can be produced in excellent yields by applying this new method.
Meteorites as catalysts for prebiotic chemistry

From outer space: Twelve meteorite specimens, representative of their major classes, catalyse the synthesis of nucleobases, carboxylic acids, aminoacids and low-molecular-weight compounds from formamide (see figure). Different chemical pathways are identified, the yields are high for a prebiotic process and the products come in rich and composite panels.
