Chemical Structure
Description
CATO supplies (9H-Fluoren-9-yl)methyl 4-amino-4-methylpiperidine-1-carboxylate (CAS 1001754-52-4), a certified reference material (molecular formula C21H24N2O2, MW 336.43 g/mol) for analytical method development and quality control.
The molecular framework of (9H-Fluoren-9-yl)methyl 4-amino-4-methylpiperidine-1-carboxylate (C21H24N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
