Compared with other compounds in its class, the molecular weight of 318.36 g/mol gives 2,3,5,6,8,9,11,12-Octahydronaphtho[2,3-b][1,4,7,10,13]pentaoxacyclopentadecine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3,5,6,8,9,11,12-Octahydronaphtho[2,3-b][1,4,7,10,13]pentaoxacyclopentadecine (CAS 17454-47-6), molecular formula C18H22O5 and molecular weight 318.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2,3,5,6,8,9,11,12-Octahydronaphtho[2,3-b][1,4,7,10,13]pentaoxacyclopentadecine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
