Chemical Structure

17a(H),21B(H)-25,30-Bisnorhopane CAS 83329-66-2 chemical structure

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.

CATO supplies 17a(H),21B(H)-25,30-Bisnorhopane (CAS 83329-66-2), a certified reference material (molecular formula C28H48, MW 384.68 g/mol) for analytical method development and quality control.

Structurally, 17a(H),21B(H)-25,30-Bisnorhopane (C28H48) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 384.68 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.
