2-(1<I>H</I>-Pyrazol-1-yl)benzaldehyde (CAS 138479-47-7), molecular formula C10H18N2O and molecular weight 182.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, 2-(1<I>H</I>-Pyrazol-1-yl)benzaldehyde is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.26 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.
