Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Chloro-1-[(2-chloro-6-fluorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (CAS 303148-71-2), molecular formula C20H13Cl2FN2O and molecular weight 387.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Chloro-1-[(2-chloro-6-fluorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (C20H13Cl2FN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 387.23 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).
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.
