Chemical Structure

5-Methyl-1-(p-tolyl)-1H-pyrazole-4-carbohydrazide CAS 618092-44-7 chemical structure

Description

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.

CATO supplies 5-Methyl-1-(p-tolyl)-1H-pyrazole-4-carbohydrazide (CAS 618092-44-7), a certified reference material (molecular formula C12H14N4O, MW 230.27 g/mol) for analytical method development and quality control.

The molecular framework of 5-Methyl-1-(p-tolyl)-1H-pyrazole-4-carbohydrazide (C12H14N4O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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