CATO supplies Benzhydryl (R)-3-methyl-2-((1R,5S)-7-oxo-3-(p-tolyl)-4-oxa-2,6-diazabicyclo[3.2.0]Hept-2-en-6-yl)but-3-enoate (CAS 67978-05-6), a certified reference material (molecular formula C29H26N2O4, MW 466.53 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Benzhydryl (R)-3-methyl-2-((1R,5S)-7-oxo-3-(p-tolyl)-4-oxa-2,6-diazabicyclo[3.2.0]Hept-2-en-6-yl)but-3-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 466.53 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).
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.
