4-Amino-N-(4-chlorophthalazin-1-yl)benzenesulfonamide CAS 16352-00-4

Description

As a certified reference material (CRM), 4-Amino-N-(4-chlorophthalazin-1-yl)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.

4-Amino-N-(4-chlorophthalazin-1-yl)benzenesulfonamide (CAS 16352-00-4) is a high-purity analytical reference standard with the molecular formula C14H11ClN4O2S and a molecular weight of 334.78 g/mol.

4-Amino-N-(4-chlorophthalazin-1-yl)benzenesulfonamide (C14H11ClN4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
