Chemical Structure
Description
CATO supplies 2-Benzyl-2,5-dimethoxy-2,5-dihydrofuran (CAS 63540-69-2), a certified reference material (molecular formula C13H16O3, MW 220.26 g/mol) for analytical method development and quality control.
The molecular framework of 2-Benzyl-2,5-dimethoxy-2,5-dihydrofuran (C13H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
