Description
CATO manufactures (2S)-2-Amino-3-(thien-2-yl)propanoic acid, N-CBZ protected 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.
CATO supplies (2S)-2-Amino-3-(thien-2-yl)propanoic acid, N-CBZ protected (CAS 146923-55-9), a certified reference material (molecular formula C15H15NO4S, MW 305.35 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (2S)-2-Amino-3-(thien-2-yl)propanoic acid, N-CBZ protected is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
