Description
Compared with other compounds in its class, the molecular weight of 250.29 g/mol gives 3-(tert-Butoxy)-4-cyclopropoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(tert-Butoxy)-4-cyclopropoxybenzoic acid (CAS 1243459-93-9), a certified reference material (molecular formula C14H18O4, MW 250.29 g/mol) for analytical method development and quality control.
3-(tert-Butoxy)-4-cyclopropoxybenzoic acid (C14H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
