Chemical Structure

3,5-Dimethylpyrazole CAS 67-51-6 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 3,5-Dimethylpyrazole.

CATO supplies 3,5-Dimethylpyrazole (CAS 67-51-6), a certified reference material (molecular formula C5H8N2, MW 96.13 g/mol) for analytical method development and quality control.

Owing to a nitrile group, 3,5-Dimethylpyrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3,5-Dimethylpyrazole 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.
