Chemical Structure

N-methyl-4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide CAS 952183-74-3 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 N-methyl-4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide.

N-methyl-4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide (CAS 952183-74-3) is a high-purity analytical reference standard with the molecular formula C13H11F3N2O3S and a molecular weight of 332.30 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, N-methyl-4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.30 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.

As a certified reference material (CRM), N-methyl-4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide 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.
