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 6-bromo-2,4-dichloropyrido[2,3-d]pyrimidine.
6-bromo-2,4-dichloropyrido[2,3-d]pyrimidine (CAS 1234616-70-6), molecular formula C7H12BrCl2N3 and molecular weight 289.00 g/mol, is a CATO reference standard with documented purity and traceability.
6-bromo-2,4-dichloropyrido[2,3-d]pyrimidine (C7H12BrCl2N3) contains a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
