Chemical Structure

1,2,3,4,6,7,8,9-Octamethyldibenzo[b,d]furan CAS 62787-25-1 chemical structure

Description

CATO supplies 1,2,3,4,6,7,8,9-Octamethyldibenzo[b,d]furan (CAS 62787-25-1), a certified reference material (molecular formula C20H24O, MW 280.40 g/mol) for analytical method development and quality control.

1,2,3,4,6,7,8,9-Octamethyldibenzo[b,d]furan (C20H24O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
