Chemical Structure

3,4,5-trimethyl-1-(prop-2-yn-1-yl)-1H-pyrazole CAS 27258-03-3 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 3,4,5-trimethyl-1-(prop-2-yn-1-yl)-1H-pyrazole.

CATO supplies 3,4,5-trimethyl-1-(prop-2-yn-1-yl)-1H-pyrazole (CAS 27258-03-3), a certified reference material (molecular formula C9H12N2, MW 148.20 g/mol) for analytical method development and quality control.

The molecular framework of 3,4,5-trimethyl-1-(prop-2-yn-1-yl)-1H-pyrazole (C9H12N2) 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.

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), 3,4,5-trimethyl-1-(prop-2-yn-1-yl)-1H-pyrazole 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.
