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 5-Fluoro-N4-methylpyrimidine-2,4-diamine.
5-Fluoro-N4-methylpyrimidine-2,4-diamine (CAS 67316-40-9), molecular formula C5H7FN4 and molecular weight 142.13 g/mol, is a CATO reference standard with documented purity and traceability.
5-Fluoro-N4-methylpyrimidine-2,4-diamine (C5H7FN4) contains a nitrile group, fluorine 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.
