Chemical Structure
Description
The occurrence of tert-Butyl (S)-2-(3-(trifluoromethyl)phenyl)piperazine-1-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl (S)-2-(3-(trifluoromethyl)phenyl)piperazine-1-carboxylate (CAS 1260595-75-2) is a high-purity analytical reference standard with the molecular formula C16H21F3N2O2 and a molecular weight of 330.35 g/mol.
Structurally, tert-Butyl (S)-2-(3-(trifluoromethyl)phenyl)piperazine-1-carboxylate (C16H21F3N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 330.35 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
