Chemical Structure

(S)-Allyl 2-aminopropanoate 4-methylbenzenesulfonate CAS 20845-17-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-Allyl 2-aminopropanoate 4-methylbenzenesulfonate.

(S)-Allyl 2-aminopropanoate 4-methylbenzenesulfonate (CAS 20845-17-4), molecular formula C7H8O3SC6H11NO2 and molecular weight 301.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-Allyl 2-aminopropanoate 4-methylbenzenesulfonate (C7H8O3SC6H11NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
