2,4-Diamino-6-((3,4-dichlorophenyl)amino)pyrimidine-5-carbonitrile (CAS 7357-32-6) is a high-purity analytical reference standard with the molecular formula C11H8Cl2N6 and a molecular weight of 295.13 g/mol.
2,4-Diamino-6-((3,4-dichlorophenyl)amino)pyrimidine-5-carbonitrile (C11H8Cl2N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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.
