3-Fluoro-n-(1,3,5-trimethyl-1h-pyrazol-4-yl)benzene-1-sulfonamide CAS 956752-67-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Fluoro-n-(1,3,5-trimethyl-1h-pyrazol-4-yl)benzene-1-sulfonamide.

CATO supplies 3-Fluoro-n-(1,3,5-trimethyl-1h-pyrazol-4-yl)benzene-1-sulfonamide (CAS 956752-67-3), a certified reference material (molecular formula C12H14FN3O2S, MW 283.32 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 3-Fluoro-n-(1,3,5-trimethyl-1h-pyrazol-4-yl)benzene-1-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
