19912-67-5 (-)-epicubenol (1S,4R,4aS,8aR)-4,7-dimethyl-1-(propan-2-yl)-1,3,4,5,6,8a-hexahydronaphthalen-4a(2H)-ol (-)-epi-cubenol epi-cubenol epicubenol CHEBI:156227 CAS 19912-67-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 19912-67-5 (-)-epicubenol (1S,4R,4aS,8aR)-4,7-dimethyl-1-(propan-2-yl)-1,3,4,5,6,8a-hexahydronaphthalen-4a(2H)-ol (-)-epi-cubenol epi-cubenol epicubenol CHEBI:156227.

19912-67-5 (-)-epicubenol (1S,4R,4aS,8aR)-4,7-dimethyl-1-(propan-2-yl)-1,3,4,5,6,8a-hexahydronaphthalen-4a(2H)-ol (-)-epi-cubenol epi-cubenol epicubenol CHEBI:156227 (CAS 19912-67-5), molecular formula C15H26O and molecular weight 222.37 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 19912-67-5 (-)-epicubenol (1S,4R,4aS,8aR)-4,7-dimethyl-1-(propan-2-yl)-1,3,4,5,6,8a-hexahydronaphthalen-4a(2H)-ol (-)-epi-cubenol epi-cubenol epicubenol CHEBI:156227 (C15H26O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 222.37 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.

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.
