Description

The occurrence of 1-(2-Chlorobenzyl)-3-(3,4-dimethoxyphenyl)-1H-pyrazole-4-carbaldehyde is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2-Chlorobenzyl)-3-(3,4-dimethoxyphenyl)-1H-pyrazole-4-carbaldehyde (CAS 590357-02-1) is a high-purity analytical reference standard with the molecular formula C19H17ClN2O3 and a molecular weight of 356.80 g/mol.

Based on its molecular formula C19H17ClN2O3, 1-(2-Chlorobenzyl)-3-(3,4-dimethoxyphenyl)-1H-pyrazole-4-carbaldehyde contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
