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-Fluoro-N2-methylpyrimidine-2,4-diamine.
6-Fluoro-N2-methylpyrimidine-2,4-diamine (CAS 165258-67-3), molecular formula C5H7FN4 and molecular weight 142.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H7FN4, 6-Fluoro-N2-methylpyrimidine-2,4-diamine contains a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 142.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
