3-(Tert-butyl)-1-(3-methylbenzyl)-1H-pyrazole-5-carbohydrazide CAS 306937-06-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Tert-butyl)-1-(3-methylbenzyl)-1H-pyrazole-5-carbohydrazide.

3-(Tert-butyl)-1-(3-methylbenzyl)-1H-pyrazole-5-carbohydrazide (CAS 306937-06-4), molecular formula C16H22N4O and molecular weight 286.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(Tert-butyl)-1-(3-methylbenzyl)-1H-pyrazole-5-carbohydrazide (C16H22N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

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.
