(R)-(9H-Fluoren-9-yl)methyl (1-chloro-4-methyl-1-oxopentan-2-yl)carbamate CAS 198544-60-4

Description

The occurrence of (R)-(9H-Fluoren-9-yl)methyl (1-chloro-4-methyl-1-oxopentan-2-yl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-(9H-Fluoren-9-yl)methyl (1-chloro-4-methyl-1-oxopentan-2-yl)carbamate (CAS 198544-60-4) is a high-purity analytical reference standard with the molecular formula C21H22ClNO3 and a molecular weight of 371.86 g/mol.

Based on its molecular formula C21H22ClNO3, (R)-(9H-Fluoren-9-yl)methyl (1-chloro-4-methyl-1-oxopentan-2-yl)carbamate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
