Chemical Structure
Description
CATO supplies 2-((4-Amino-1-methyl-1H-pyrazol-3-yl)thio)acetic acid (CAS 1431963-07-3), a certified reference material (molecular formula C6H9N3O2SHCl, MW 223.68 g/mol) for analytical method development and quality control.
The molecular framework of 2-((4-Amino-1-methyl-1H-pyrazol-3-yl)thio)acetic acid (C6H9N3O2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 2-((4-Amino-1-methyl-1H-pyrazol-3-yl)thio)acetic 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.
