Description
As a certified reference material (CRM), Sodium 3-amino-5-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)-4-methylbenzenesulfonate 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.
Sodium 3-amino-5-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)-4-methylbenzenesulfonate (CAS 84100-32-3) is a high-purity analytical reference standard with the molecular formula C11H8ClF2N4O3SNa and a molecular weight of 372.71 g/mol.
Sodium 3-amino-5-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)-4-methylbenzenesulfonate (C11H8ClF2N4O3SNa) contains a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
