Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{4-[2-(pyridin-4-yl)pyrimidin-4-yl]phenyl}-1H-1,3-benzodiazole.
CATO supplies 1-{4-[2-(pyridin-4-yl)pyrimidin-4-yl]phenyl}-1H-1,3-benzodiazole (CAS 685106-80-3), a certified reference material (molecular formula C22H15N5, MW 349.39 g/mol) for analytical method development and quality control.
Structurally, 1-{4-[2-(pyridin-4-yl)pyrimidin-4-yl]phenyl}-1H-1,3-benzodiazole (C22H15N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 349.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
