Chemical Structure
Description
CATO supplies 3-Methyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine (CAS 118055-08-6), a certified reference material (molecular formula C8H12N2, MW 136.19 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine (C8H12N2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 3-Methyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
