Chemical Structure

3,4-Dihydro-2,2-dimethyl-2H-naphtho[1,2-b]pyran CAS 16274-33-2 chemical structure

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 3,4-Dihydro-2,2-dimethyl-2H-naphtho[1,2-b]pyran (CAS 16274-33-2), a certified reference material (molecular formula C15H16O, MW 212.29 g/mol) for analytical method development and quality control.

3,4-Dihydro-2,2-dimethyl-2H-naphtho[1,2-b]pyran (C15H16O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
