Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1'-(Dihydropyrimidine-1,3(2H,4H)-diyl)bis(hexadecan-1-one).
CATO supplies 1,1'-(Dihydropyrimidine-1,3(2H,4H)-diyl)bis(hexadecan-1-one) (CAS 32644-62-5), a certified reference material (molecular formula C13H16ClFN2, MW 254.73 g/mol) for analytical method development and quality control.
Structurally, 1,1'-(Dihydropyrimidine-1,3(2H,4H)-diyl)bis(hexadecan-1-one) (C13H16ClFN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 254.73 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
