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.

1-(3-Methylphenyl)-1H-pyrazole-4-carbaldehyde (CAS 400876-64-4), molecular formula C11H10N2O and molecular weight 186.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(3-Methylphenyl)-1H-pyrazole-4-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 186.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
