Chemical Structure

4-Chloropyrazolo[1,5-a]pyridin-5-amine CAS 2097329-59-2 chemical structure

Description

The occurrence of 4-Chloropyrazolo[1,5-a]pyridin-5-amine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloropyrazolo[1,5-a]pyridin-5-amine (CAS 2097329-59-2), molecular formula C7H6ClN3 and molecular weight 167.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloropyrazolo[1,5-a]pyridin-5-amine (C7H6ClN3) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4-Chloropyrazolo[1,5-a]pyridin-5-amine 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.
