Chemical Structure
Description
The occurrence of Methyl 1-(3-(thiophen-2-yl)-3-(2,2,2-trifluoroacetamido)propanoyl)piperidine-4-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 1-(3-(thiophen-2-yl)-3-(2,2,2-trifluoroacetamido)propanoyl)piperidine-4-carboxylate (CAS 439107-50-3) is a high-purity analytical reference standard with the molecular formula C16H19F3N2O4S and a molecular weight of 392.39 g/mol.
Methyl 1-(3-(thiophen-2-yl)-3-(2,2,2-trifluoroacetamido)propanoyl)piperidine-4-carboxylate (C16H19F3N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Methyl 1-(3-(thiophen-2-yl)-3-(2,2,2-trifluoroacetamido)propanoyl)piperidine-4-carboxylate 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.
