Chemical Structure
Description
Structurally, Tert-butyl 6-((4-cyano-2-fluorobenzyl)oxy)-3',6'-dihydro-[2,4'-bipyridine]-1'(2'H)-carboxylate (C23H24FN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 409.45 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).
Tert-butyl 6-((4-cyano-2-fluorobenzyl)oxy)-3',6'-dihydro-[2,4'-bipyridine]-1'(2'H)-carboxylate (CAS 2428642-40-2), molecular formula C23H24FN3O3 and molecular weight 409.45 g/mol, is a CATO reference standard with documented purity and traceability.
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.
