Chemical Structure
Description
The occurrence of Sodium 4-((5-chloro-6-methyl-2-(methylsulfonyl)pyrimidin-4-yl)amino)-5-hydroxynaphthalene-2,7-disulfonate is closely related to a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium 4-((5-chloro-6-methyl-2-(methylsulfonyl)pyrimidin-4-yl)amino)-5-hydroxynaphthalene-2,7-disulfonate (CAS 55329-60-7), a certified reference material (molecular formula C16H12ClN3O9S3Na, MW 544.90 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 4-((5-chloro-6-methyl-2-(methylsulfonyl)pyrimidin-4-yl)amino)-5-hydroxynaphthalene-2,7-disulfonate (C16H12ClN3O9S3Na) is characterized by a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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), Sodium 4-((5-chloro-6-methyl-2-(methylsulfonyl)pyrimidin-4-yl)amino)-5-hydroxynaphthalene-2,7-disulfonate 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.
