Chemical Structure
Description
(9H-fluoren-9-yl)methyl (R)-(3-hydroxy-2-methylpropyl)carbamate (CAS 1265892-29-2) is a high-purity analytical reference standard with the molecular formula C19H21NO3 and a molecular weight of 311.37 g/mol.
The molecular framework of (9H-fluoren-9-yl)methyl (R)-(3-hydroxy-2-methylpropyl)carbamate (C19H21NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (9H-fluoren-9-yl)methyl (R)-(3-hydroxy-2-methylpropyl)carbamate 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.
