Chemical Structure
Description
The occurrence of 5-Allyl-6-methyl-N-(4-nitrophenyl)-2-phenylpyrimidin-4-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Allyl-6-methyl-N-(4-nitrophenyl)-2-phenylpyrimidin-4-amine (CAS 330819-79-9), a certified reference material (molecular formula C20H18N4O2, MW 346.38 g/mol) for analytical method development and quality control.
5-Allyl-6-methyl-N-(4-nitrophenyl)-2-phenylpyrimidin-4-amine (C20H18N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
