Chemical Structure
Description
CATO supplies Methyl 2-[(2-aminoethyl)sulfanyl]acetate hydrochloride (CAS 40642-85-1), a certified reference material (molecular formula C5H11NO2SHCl, MW 185.67 g/mol) for analytical method development and quality control.
Methyl 2-[(2-aminoethyl)sulfanyl]acetate hydrochloride (C5H11NO2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Methyl 2-[(2-aminoethyl)sulfanyl]acetate hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
