Description
CATO supplies 1-Benzyl-3-(4-methylphenyl)-1h-pyrazole-4-carbaldehyde (CAS 956783-07-6), a certified reference material (molecular formula C18H16N2O, MW 276.33 g/mol) for analytical method development and quality control.
Structurally, 1-Benzyl-3-(4-methylphenyl)-1h-pyrazole-4-carbaldehyde (C18H16N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 276.33 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
