Chemical Structure
Description
CATO supplies Ethyl 6-methyl-1-oxaspiro[2.6]nonane-2-carboxylate (CAS 1561409-18-4), a certified reference material (molecular formula C12H20O3, MW 212.29 g/mol) for analytical method development and quality control.
Ethyl 6-methyl-1-oxaspiro[2.6]nonane-2-carboxylate (C12H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
