(2R)-2-Acetamido-3-((1-hydroxybut-3-en-2-yl)thio)propanoic acid CAS 144889-51-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R)-2-Acetamido-3-((1-hydroxybut-3-en-2-yl)thio)propanoic acid.

(2R)-2-Acetamido-3-((1-hydroxybut-3-en-2-yl)thio)propanoic acid (CAS 144889-51-0), molecular formula C9H15NO4S and molecular weight 233.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2R)-2-Acetamido-3-((1-hydroxybut-3-en-2-yl)thio)propanoic acid (C9H15NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid 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.

CATO manufactures (2R)-2-Acetamido-3-((1-hydroxybut-3-en-2-yl)thio)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
