Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.25 g/mol gives 5-Methyl-2-morpholinobenzo[d]oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methyl-2-morpholinobenzo[d]oxazole (CAS 2881-53-0), a certified reference material (molecular formula C12H14N2O2, MW 218.25 g/mol) for analytical method development and quality control.
5-Methyl-2-morpholinobenzo[d]oxazole (C12H14N2O2) contains an amino-acid-derived structure, an amide 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.
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.
