Chemical Structure
Description
5-{[(tert-butoxy)carbonyl]amino}-3-(trifluoromethyl)pentanoic acid (CAS 1258640-67-3) is a high-purity analytical reference standard with the molecular formula C11H18F3NO4 and a molecular weight of 285.26 g/mol.
5-{[(tert-butoxy)carbonyl]amino}-3-(trifluoromethyl)pentanoic acid (C11H18F3NO4) contains an amide group, a carboxylic acid 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), 5-{[(tert-butoxy)carbonyl]amino}-3-(trifluoromethyl)pentanoic acid 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.
