Chemical Structure

3-tert-butyl-1-methyl-1H-pyrazole CAS 141665-16-9 chemical structure

Description

3-tert-butyl-1-methyl-1H-pyrazole (CAS 141665-16-9) is a high-purity analytical reference standard with the molecular formula C8H14N2 and a molecular weight of 138.21 g/mol.

The molecular framework of 3-tert-butyl-1-methyl-1H-pyrazole (C8H14N2) is characterized by 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).

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

As a certified reference material (CRM), 3-tert-butyl-1-methyl-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.
