Chemical Structure

5-(Methylthio)-1-phenyl-1H-pyrazole-3-carbaldehyde CAS 871110-04-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Methylthio)-1-phenyl-1H-pyrazole-3-carbaldehyde.

5-(Methylthio)-1-phenyl-1H-pyrazole-3-carbaldehyde (CAS 871110-04-2) is a high-purity analytical reference standard with the molecular formula C11H10N2OS and a molecular weight of 218.27 g/mol.

The molecular framework of 5-(Methylthio)-1-phenyl-1H-pyrazole-3-carbaldehyde (C11H10N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
