Chemical Structure

(S)-4-Amino-3-p-tolylbutanoicacid CAS 67112-57-6 chemical structure

Description

The occurrence of (S)-4-Amino-3-p-tolylbutanoicacid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-4-Amino-3-p-tolylbutanoicacid (CAS 67112-57-6), molecular formula C20H16O4 and molecular weight 320.34 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-4-Amino-3-p-tolylbutanoicacid (C20H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
