Chemical Structure
Description
2-(tert-Butoxy)-5-cyclopropoxy-4-ethylpyridine (CAS 1243327-58-3), molecular formula C14H21NO2 and molecular weight 235.32 g/mol, is a CATO reference standard with documented purity and traceability.
2-(tert-Butoxy)-5-cyclopropoxy-4-ethylpyridine (C14H21NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
