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.
(13bR)-5,7-Dihydro-2,8-dimethoxy-3H-cyclopenta[6,7]cycloocta[2,1-a:3,4-a']dinaphthalene (CAS 1417714-07-8), molecular formula C29H24O2 and molecular weight 404.50 g/mol, is a CATO reference standard with documented purity and traceability.
(13bR)-5,7-Dihydro-2,8-dimethoxy-3H-cyclopenta[6,7]cycloocta[2,1-a:3,4-a']dinaphthalene (C29H24O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
