Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(3,4-dihydro-2H-1,4-benzoxazin-6-yl)thiophene-2-carboxamide hydrochloride (CAS 1209773-69-2), molecular formula C13H12N2O2SHCl and molecular weight 296.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(3,4-dihydro-2H-1,4-benzoxazin-6-yl)thiophene-2-carboxamide hydrochloride (C13H12N2O2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 5-(3,4-dihydro-2H-1,4-benzoxazin-6-yl)thiophene-2-carboxamide 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.
