Chemical Structure
Description
(9H-Fluoren-9-yl)methyl benzylidenecarbamate (CAS 163226-38-8), molecular formula C22H17NO2 and molecular weight 327.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H17NO2, (9H-Fluoren-9-yl)methyl benzylidenecarbamate contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 327.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures (9H-Fluoren-9-yl)methyl benzylidenecarbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
