Chemical Structure
Description
23702-49-0 5-Phenanthro(4,5-bcd)pyran-5-one 5H-Phenanthro(4,5-bcd)pyran-5-one CCRIS 2211 (C15H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
23702-49-0 5-Phenanthro(4,5-bcd)pyran-5-one 5H-Phenanthro(4,5-bcd)pyran-5-one CCRIS 2211 (CAS 23702-49-0), molecular formula C15H8O2 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.
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.
