Chemical Structure
Description
CATO supplies 2-[(4,4-Diethoxy-2-butyn-1-yl)oxy]tetrahydropyran (CAS 99805-29-5), a certified reference material (molecular formula C13H22O4, MW 242.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H22O4, 2-[(4,4-Diethoxy-2-butyn-1-yl)oxy]tetrahydropyran contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
