Chemical Structure
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.
CATO supplies 1-(3-Chlorophenyl)-N-(2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)methanesulfonamide (CAS 1235268-86-6), a certified reference material (molecular formula C14H18ClN3O2S, MW 327.83 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, chlorine substitution, 1-(3-Chlorophenyl)-N-(2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)methanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.83 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).
As a certified reference material (CRM), 1-(3-Chlorophenyl)-N-(2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)methanesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
