Chemical Structure
Description
5-(5,5-Dimethyl-1,3-dioxan-2-yl)-α-[5-(5,5-dimethyl-1,3-dioxan-2-yl)-2-methoxyphenyl]-2-methoxy-α-(4-methoxyphenyl)benzenemethanol (C34H42O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
5-(5,5-Dimethyl-1,3-dioxan-2-yl)-α-[5-(5,5-dimethyl-1,3-dioxan-2-yl)-2-methoxyphenyl]-2-methoxy-α-(4-methoxyphenyl)benzenemethanol (CAS 235106-88-4) is a high-purity analytical reference standard with the molecular formula C34H42O8 and a molecular weight of 578.69 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.
