Methyl 9,10-dihydro-9,10-ethanoanthracene-11-carboxylate CAS 13294-86-5

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.

Methyl 9,10-dihydro-9,10-ethanoanthracene-11-carboxylate (CAS 13294-86-5), molecular formula C18H16O2 and molecular weight 264.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 9,10-dihydro-9,10-ethanoanthracene-11-carboxylate (C18H16O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 264.32 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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