Chemical Structure

Calcium (S)-2-amino-4-carboxybutanoate CAS 5996-22-5 chemical structure

Description

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.

CATO supplies Calcium (S)-2-amino-4-carboxybutanoate (CAS 5996-22-5), a certified reference material (molecular formula C5H8NO4Ca, MW 186.20 g/mol) for analytical method development and quality control.

Calcium (S)-2-amino-4-carboxybutanoate (C5H8NO4Ca) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
