Chemical Structure
Description
The occurrence of (9H-Fluoren-9-yl)methyl (4-formylphenyl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (9H-Fluoren-9-yl)methyl (4-formylphenyl)carbamate (CAS 475160-85-1), a certified reference material (molecular formula C22H17NO3, MW 343.38 g/mol) for analytical method development and quality control.
(9H-Fluoren-9-yl)methyl (4-formylphenyl)carbamate (C22H17NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
