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 4-Amino-N-(1,6-dihydro-4-methyl-6-oxo-2-pyrimidinyl)benzenesulfonamide.
4-Amino-N-(1,6-dihydro-4-methyl-6-oxo-2-pyrimidinyl)benzenesulfonamide (CAS 6947-80-4) is a high-purity analytical reference standard with the molecular formula C11H12N4O3S and a molecular weight of 280.30 g/mol.
The molecular framework of 4-Amino-N-(1,6-dihydro-4-methyl-6-oxo-2-pyrimidinyl)benzenesulfonamide (C11H12N4O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-Amino-N-(1,6-dihydro-4-methyl-6-oxo-2-pyrimidinyl)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.
