Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (Naphthalene-1,4-diylbis(3,1-phenylene))dimethanol (CAS 1349708-87-7), a certified reference material (molecular formula C24H20O2, MW 340.41 g/mol) for analytical method development and quality control.
Based on its molecular formula C24H20O2, (Naphthalene-1,4-diylbis(3,1-phenylene))dimethanol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.41 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).
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.
