CATO supplies 20007-87-8 Cyclopenin Cyclopenine (8CI) 4-Methyl-3'-phenylspiro(3H-1,4-benzodiazepine-3,2'-oxirane)-2,5(1H,4H)-dione Spiro(3H-1,4-benzodiazepine-3,2'-oxirane)-2,5(1H,4H)-dione, 4-methyl-3'-phenyl-, cis-(-)- (9CI) (-)-Cyclopenin (-)-Cyclopenine NSC 114538 (CAS 20007-87-8), a certified reference material (molecular formula C17H14N2O3, MW 294.30 g/mol) for analytical method development and quality control.
Structurally, 20007-87-8 Cyclopenin Cyclopenine (8CI) 4-Methyl-3'-phenylspiro(3H-1,4-benzodiazepine-3,2'-oxirane)-2,5(1H,4H)-dione Spiro(3H-1,4-benzodiazepine-3,2'-oxirane)-2,5(1H,4H)-dione, 4-methyl-3'-phenyl-, cis-(-)- (9CI) (-)-Cyclopenin (-)-Cyclopenine NSC 114538 (C17H14N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 294.30 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
