Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Dihydro-1,4-methanonaphthalene-5,8-diyl diacetate.
CATO supplies 1,4-Dihydro-1,4-methanonaphthalene-5,8-diyl diacetate (CAS 7213-65-2), a certified reference material (molecular formula C11H10O2C2H4O2, MW 234.25 g/mol) for analytical method development and quality control.
1,4-Dihydro-1,4-methanonaphthalene-5,8-diyl diacetate (C11H10O2C2H4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
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.
