Chemical Structure
Description
Tert-butyl (3,3-difluorocyclobutyl)(methyl)carbamate (CAS 2299776-40-0) is a high-purity analytical reference standard with the molecular formula C10H17F2NO2 and a molecular weight of 221.24 g/mol.
Based on its molecular formula C10H17F2NO2, Tert-butyl (3,3-difluorocyclobutyl)(methyl)carbamate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 221.24 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.
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.
