Chemical Structure

(R)-3-Amino-4-(benzo[b]thiophen-3-yl)butanoic acid CAS 269398-95-0 chemical structure

Description

(R)-3-Amino-4-(benzo[b]thiophen-3-yl)butanoic acid (C12H13NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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.

CATO supplies (R)-3-Amino-4-(benzo[b]thiophen-3-yl)butanoic acid (CAS 269398-95-0), a certified reference material (molecular formula C12H13NO2S, MW 235.30 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
