(S)-2-Amino-4-cyanobutanoic acid CAS 6232-22-0

Description

Compared with other compounds in its class, the molecular weight of 128.13 g/mol gives (S)-2-Amino-4-cyanobutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-2-Amino-4-cyanobutanoic acid (CAS 6232-22-0), molecular formula C5H8N2O2 and molecular weight 128.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-Amino-4-cyanobutanoic acid (C5H8N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
