Chemical Structure

1-benzyl-3-(3-methylphenyl)-1H-pyrazole-4-carbaldehyde CAS 956753-10-9 chemical structure

Description

The molecular framework of 1-benzyl-3-(3-methylphenyl)-1H-pyrazole-4-carbaldehyde (C18H16N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 1-benzyl-3-(3-methylphenyl)-1H-pyrazole-4-carbaldehyde (CAS 956753-10-9), a certified reference material (molecular formula C18H16N2O, MW 276.33 g/mol) for analytical method development and quality control.

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.
