Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 2-nitrothiazole-4-carboxylate (CAS 43028-99-5) is a high-purity analytical reference standard with the molecular formula C6H6N2O4S and a molecular weight of 202.19 g/mol.
The molecular framework of Ethyl 2-nitrothiazole-4-carboxylate (C6H6N2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Ethyl 2-nitrothiazole-4-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.
