Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,4-Dimethoxypyrimidin-5-yl)benzonitrile.
4-(2,4-Dimethoxypyrimidin-5-yl)benzonitrile (CAS 1101167-59-2), molecular formula C13H11N3O2 and molecular weight 241.25 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2,4-Dimethoxypyrimidin-5-yl)benzonitrile (C13H11N3O2) contains a nitrogen-containing heterocyclic scaffold, 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.
