Chemical Structure

N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine CAS 100496-03-5 chemical structure

Description

N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (CAS 100496-03-5) is a high-purity analytical reference standard with the molecular formula C9H17NO4S and a molecular weight of 235.30 g/mol.

The molecular framework of N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (C9H17NO4S) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine 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.
