3-(4-Butoxyphenyl)-1H-pyrazole-4-carbaldehyde CAS 696646-80-7

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.

3-(4-Butoxyphenyl)-1H-pyrazole-4-carbaldehyde (CAS 696646-80-7) is a high-purity analytical reference standard with the molecular formula C14H16N2O2 and a molecular weight of 244.29 g/mol.

Structurally, 3-(4-Butoxyphenyl)-1H-pyrazole-4-carbaldehyde (C14H16N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 244.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
