Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.81 g/mol gives 3-[2-(diethylamino)ethyl]-7-hydroxy-4-methylcoumarin hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-[2-(diethylamino)ethyl]-7-hydroxy-4-methylcoumarin hydrochloride (CAS 15776-59-7) is a high-purity analytical reference standard with the molecular formula C16H21NO3HCl and a molecular weight of 311.81 g/mol.
3-[2-(diethylamino)ethyl]-7-hydroxy-4-methylcoumarin hydrochloride (C16H21NO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
