Chemical Structure
Description
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.
(2s)-2-Amino-n-hydroxy-4-(methylsulfanyl)butanamide (CAS 19253-87-3), molecular formula C5H12N2O2S and molecular weight 164.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2s)-2-Amino-n-hydroxy-4-(methylsulfanyl)butanamide (C5H12N2O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (2s)-2-Amino-n-hydroxy-4-(methylsulfanyl)butanamide 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.
