Chemical Structure
Description
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.
Tert-butyl ((1R,2S,4R)-4-amino-2-fluorocyclohexyl)carbamate (CAS 2165684-15-9) is a high-purity analytical reference standard with the molecular formula C11H21FN2O2 and a molecular weight of 232.30 g/mol.
Structurally, Tert-butyl ((1R,2S,4R)-4-amino-2-fluorocyclohexyl)carbamate (C11H21FN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 232.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
