N-(2-Hydroxyethyl)-N-(3-hydroxypropyl)-4-methylbenzenesulfonamide CAS 6965-77-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2-Hydroxyethyl)-N-(3-hydroxypropyl)-4-methylbenzenesulfonamide.

N-(2-Hydroxyethyl)-N-(3-hydroxypropyl)-4-methylbenzenesulfonamide (CAS 6965-77-1), molecular formula C12H19NO4S and molecular weight 273.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(2-Hydroxyethyl)-N-(3-hydroxypropyl)-4-methylbenzenesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.35 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-(2-Hydroxyethyl)-N-(3-hydroxypropyl)-4-methylbenzenesulfonamide 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.
