Chemical Structure

6-Methylpyrazolo[1,5-a]pyridine CAS 139452-20-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

6-Methylpyrazolo[1,5-a]pyridine (CAS 139452-20-3), molecular formula C8H8N2 and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Methylpyrazolo[1,5-a]pyridine (C8H8N2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
