5-(4-Chlorophthalazin-1-yl)-N-(2-hydroxyethyl)-2-methylbenzenesulfonamide CAS 733801-91-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-Chlorophthalazin-1-yl)-N-(2-hydroxyethyl)-2-methylbenzenesulfonamide.

5-(4-Chlorophthalazin-1-yl)-N-(2-hydroxyethyl)-2-methylbenzenesulfonamide (CAS 733801-91-7) is a high-purity analytical reference standard with the molecular formula C17H16ClN3O3S and a molecular weight of 377.85 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(4-Chlorophthalazin-1-yl)-N-(2-hydroxyethyl)-2-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-(4-Chlorophthalazin-1-yl)-N-(2-hydroxyethyl)-2-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.
