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 3-amino-1H-pyrazole-5-carboxylate hydrochloride (CAS 1298034-20-4), molecular formula C6H9N3O2HCl and molecular weight 191.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-amino-1H-pyrazole-5-carboxylate hydrochloride (C6H9N3O2HCl) is characterized by an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Ethyl 3-amino-1H-pyrazole-5-carboxylate hydrochloride 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.
