CATO supplies methyl 4-amino-1,2,5-oxadiazole-3-carboxylate (CAS 159013-94-2), a certified reference material (molecular formula C4H9N3O3, MW 147.13 g/mol) for analytical method development and quality control.
The molecular framework of methyl 4-amino-1,2,5-oxadiazole-3-carboxylate (C4H9N3O3) is characterized by an amino-acid-derived structure, an amide 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 methyl 4-amino-1,2,5-oxadiazole-3-carboxylate 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.
