Description

The occurrence of 1-Phenyl-3-[4-(propylsulfanyl)phenyl]-1H-pyrazole-4-carbaldehyde is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Phenyl-3-[4-(propylsulfanyl)phenyl]-1H-pyrazole-4-carbaldehyde (CAS 882234-97-1), molecular formula C19H18N2OS and molecular weight 322.42 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Phenyl-3-[4-(propylsulfanyl)phenyl]-1H-pyrazole-4-carbaldehyde (C19H18N2OS) contains a steroid core, an amide group, sulfur-containing functionality, 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 322.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
