Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-4-((5-chloro-4-(methylamino)pyrimidin-2-yl)amino)-5-methoxybenzoic acid.
CATO supplies 2-Chloro-4-((5-chloro-4-(methylamino)pyrimidin-2-yl)amino)-5-methoxybenzoic acid (CAS 1441722-24-2), a certified reference material (molecular formula C13H12Cl2N4O3, MW 343.17 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-4-((5-chloro-4-(methylamino)pyrimidin-2-yl)amino)-5-methoxybenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.17 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloro-4-((5-chloro-4-(methylamino)pyrimidin-2-yl)amino)-5-methoxybenzoic acid 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.
