5,6-DIhydro-2,4-dimethyl-4-phenyl-4H-benzo[b]furo[3′,2′:6,7]cyclohepta[1,2-d]furan CAS 220542-81-4

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.

5,6-DIhydro-2,4-dimethyl-4-phenyl-4H-benzo[b]furo[3′,2′:6,7]cyclohepta[1,2-d]furan (CAS 220542-81-4) is a high-purity analytical reference standard with the molecular formula C23H20O2 and a molecular weight of 328.40 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5,6-DIhydro-2,4-dimethyl-4-phenyl-4H-benzo[b]furo[3′,2′:6,7]cyclohepta[1,2-d]furan is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
