Chemical Structure

N,N'-((3aR,4R,7R,7aS)-2,2-dimethyl-5-(trimethylsilyl)-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide CAS 1998128-25-8 chemical structure

Description

The occurrence of N,N'-((3aR,4R,7R,7aS)-2,2-dimethyl-5-(trimethylsilyl)-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,N'-((3aR,4R,7R,7aS)-2,2-dimethyl-5-(trimethylsilyl)-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide (CAS 1998128-25-8) is a high-purity analytical reference standard with the molecular formula C26H32N2O4Si and a molecular weight of 464.63 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N,N'-((3aR,4R,7R,7aS)-2,2-dimethyl-5-(trimethylsilyl)-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.63 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
