Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2aR,2a1S,5R,5aS,8aR)-5,8-Dimethyl-2a,2a1,3,4,5,5a,6,8a-octahydro-2H-naphtho[1,8-bc]furan-2-one.
(2aR,2a1S,5R,5aS,8aR)-5,8-Dimethyl-2a,2a1,3,4,5,5a,6,8a-octahydro-2H-naphtho[1,8-bc]furan-2-one (CAS 82442-48-6), molecular formula C13H18O2 and molecular weight 206.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2aR,2a1S,5R,5aS,8aR)-5,8-Dimethyl-2a,2a1,3,4,5,5a,6,8a-octahydro-2H-naphtho[1,8-bc]furan-2-one (C13H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
