Chemical Structure

(4Z)-3-Methyl-4-(2-phenylhydrazin-1-ylidene)-4,5-dihydro-1H-pyrazol-5-one CAS 53847-68-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4Z)-3-Methyl-4-(2-phenylhydrazin-1-ylidene)-4,5-dihydro-1H-pyrazol-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

(4Z)-3-Methyl-4-(2-phenylhydrazin-1-ylidene)-4,5-dihydro-1H-pyrazol-5-one (CAS 53847-68-0) is a high-purity analytical reference standard with the molecular formula C10H10N4O and a molecular weight of 202.21 g/mol.

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.

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.
