Chemical Structure
Description
(1R,6S)-1,6-Dimethyl-9-(propan-2-ylidene)-5,12-dioxatricyclo[9.1.0.04,6]dodecan-8-one 32179-18-3 ST24033625 (C15H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(1R,6S)-1,6-Dimethyl-9-(propan-2-ylidene)-5,12-dioxatricyclo[9.1.0.04,6]dodecan-8-one 32179-18-3 ST24033625 (CAS 32179-18-3) is a high-purity analytical reference standard with the molecular formula C15H22O3 and a molecular weight of 250.33 g/mol.
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.
