Chemical Structure
Description
The occurrence of 4H,5H,6H,7H-[1,2]oxazolo[4,5-c]pyridine-3-carboxylic acid hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4H,5H,6H,7H-[1,2]oxazolo[4,5-c]pyridine-3-carboxylic acid hydrochloride (CAS 1803587-35-0), molecular formula C7H8N2O3HCl and molecular weight 204.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4H,5H,6H,7H-[1,2]oxazolo[4,5-c]pyridine-3-carboxylic acid hydrochloride (C7H8N2O3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4H,5H,6H,7H-[1,2]oxazolo[4,5-c]pyridine-3-carboxylic acid 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.
