1-(2-Methoxyphenyl)-5-methyl-1H-pyrazole-4-carbohydrazide CAS 618092-56-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Methoxyphenyl)-5-methyl-1H-pyrazole-4-carbohydrazide.

CATO supplies 1-(2-Methoxyphenyl)-5-methyl-1H-pyrazole-4-carbohydrazide (CAS 618092-56-1), a certified reference material (molecular formula C12H14N4O2, MW 246.27 g/mol) for analytical method development and quality control.

The molecular framework of 1-(2-Methoxyphenyl)-5-methyl-1H-pyrazole-4-carbohydrazide (C12H14N4O2) is characterized by an amino-acid-derived structure, 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.
