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 2,4-Diamino-6-((4-bromophenyl)amino)pyrimidine-5-carboxamide.
CATO supplies 2,4-Diamino-6-((4-bromophenyl)amino)pyrimidine-5-carboxamide (CAS 91820-04-1), a certified reference material (molecular formula C11H11BrN6O, MW 323.15 g/mol) for analytical method development and quality control.
2,4-Diamino-6-((4-bromophenyl)amino)pyrimidine-5-carboxamide (C11H11BrN6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
