Chemical Structure

2-Ethylpyrazolo[1,5-a]pyridine CAS 475174-65-3 chemical structure

Description

The molecular framework of 2-Ethylpyrazolo[1,5-a]pyridine (C9H10N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

CATO supplies 2-Ethylpyrazolo[1,5-a]pyridine (CAS 475174-65-3), a certified reference material (molecular formula C9H10N2, MW 146.19 g/mol) for analytical method development and quality control.

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 2-Ethylpyrazolo[1,5-a]pyridine 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.
