Chemical Structure
Description
CATO supplies 2,2'-(((Naphthalene-1,5-diylbis(oxy))bis(ethane-2,1-diyl))bis(oxy))bis(ethan-1-ol) (CAS 136133-14-7), a certified reference material (molecular formula C18H24O6, MW 336.38 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H24O6, 2,2'-(((Naphthalene-1,5-diylbis(oxy))bis(ethane-2,1-diyl))bis(oxy))bis(ethan-1-ol) contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
