Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (8E)-8-[(Benzyloxy)imino]-4,10-dithia-1-azatetracyclo[9.7.0.0^{3,7}.0^{12,17}]octadeca-3(7),5,12(17),13,15-pentaen-18-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.52 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).
(8E)-8-[(Benzyloxy)imino]-4,10-dithia-1-azatetracyclo[9.7.0.0^{3,7}.0^{12,17}]octadeca-3(7),5,12(17),13,15-pentaen-18-one (CAS 866008-40-4), molecular formula C22H18N2O2S2 and molecular weight 406.52 g/mol, is a CATO reference standard with documented purity and traceability.
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.
