Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (9H-fluoren-9-yl)methyl (R)-(2-(hydroxymethyl)-3-methylbutyl)carbamate.
(9H-fluoren-9-yl)methyl (R)-(2-(hydroxymethyl)-3-methylbutyl)carbamate (CAS 1265892-38-3) is a high-purity analytical reference standard with the molecular formula C21H25NO3 and a molecular weight of 339.43 g/mol.
Based on its molecular formula C21H25NO3, (9H-fluoren-9-yl)methyl (R)-(2-(hydroxymethyl)-3-methylbutyl)carbamate 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 339.43 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (9H-fluoren-9-yl)methyl (R)-(2-(hydroxymethyl)-3-methylbutyl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
