Description
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.
Methyl 1,5-dibenzyl-3-(2-chlorophenyl)-4,6-dioxo-octahydropyrrolo[3,4-c]pyrrole-1-carboxylate (CAS 321521-59-9) is a high-purity analytical reference standard with the molecular formula C28H25ClN2O4 and a molecular weight of 488.96 g/mol.
Structurally, Methyl 1,5-dibenzyl-3-(2-chlorophenyl)-4,6-dioxo-octahydropyrrolo[3,4-c]pyrrole-1-carboxylate (C28H25ClN2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 488.96 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
