3-amino-5H,6H,7H-cyclopenta[c]pyridine-4-carboxylic acid hydrobromide CAS 1820705-02-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-amino-5H,6H,7H-cyclopenta[c]pyridine-4-carboxylic acid hydrobromide.

CATO supplies 3-amino-5H,6H,7H-cyclopenta[c]pyridine-4-carboxylic acid hydrobromide (CAS 1820705-02-9), a certified reference material (molecular formula C9H10N2O2HBr, MW 259.10 g/mol) for analytical method development and quality control.

3-amino-5H,6H,7H-cyclopenta[c]pyridine-4-carboxylic acid hydrobromide (C9H10N2O2HBr) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 3-amino-5H,6H,7H-cyclopenta[c]pyridine-4-carboxylic acid hydrobromide 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.
