Chemical Structure
Description
CATO supplies 4-(2-Phenyl-6-(p-tolyloxy)pyrimidin-4-yl)morpholine (CAS 339018-78-9), a certified reference material (molecular formula C21H21N3O2, MW 347.41 g/mol) for analytical method development and quality control.
Structurally, 4-(2-Phenyl-6-(p-tolyloxy)pyrimidin-4-yl)morpholine (C21H21N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 347.41 g/mol, it falls into the moderately-high-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.
