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-Chloro-N5-methylpyrimidine-4,5-diamine.
6-Chloro-N5-methylpyrimidine-4,5-diamine (CAS 55286-10-7), molecular formula C5H7ClN4 and molecular weight 158.59 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloro-N5-methylpyrimidine-4,5-diamine (C5H7ClN4) contains 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. 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.
