Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-pyrimidin-2-ol.
4-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-pyrimidin-2-ol (CAS 1311279-04-5) is a high-purity analytical reference standard with the molecular formula C18H15F3N4O and a molecular weight of 360.33 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-pyrimidin-2-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
