Description
484-14-0 7-hydroxy--2H-1-benzopyran-2-one 7-hydroxy-8-(3-methyl-but-2-enyl)coumarin 7-hydroxy-8-prenylcoumarin 8-(3-methylbut-2-en-1-yl)umbelliferone 8-prenylumbelliferone CHEBI:81485 osthenol (CAS 484-14-0), molecular formula C14H14O3 and molecular weight 230.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H14O3, 484-14-0 7-hydroxy--2H-1-benzopyran-2-one 7-hydroxy-8-(3-methyl-but-2-enyl)coumarin 7-hydroxy-8-prenylcoumarin 8-(3-methylbut-2-en-1-yl)umbelliferone 8-prenylumbelliferone CHEBI:81485 osthenol contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 230.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
