CATO supplies Bicyclo[4.4.1]undeca-1,3,5,7,9-pentaene (CAS 2443-46-1), a certified reference material (molecular formula C11H10, MW 142.20 g/mol) for analytical method development and quality control.
Bicyclo[4.4.1]undeca-1,3,5,7,9-pentaene (C11H10) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
