(E)-3-(2,4-Dichlorophenyl)-N'-(4-hydroxybenzylidene)-1H-pyrazole-5-carbohydrazide CAS 1285681-86-8

Description

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.

CATO supplies (E)-3-(2,4-Dichlorophenyl)-N'-(4-hydroxybenzylidene)-1H-pyrazole-5-carbohydrazide (CAS 1285681-86-8), a certified reference material (molecular formula C17H12Cl2N4O2, MW 375.21 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (E)-3-(2,4-Dichlorophenyl)-N'-(4-hydroxybenzylidene)-1H-pyrazole-5-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 375.21 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.

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.
