Chemical Structure
Description
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.
2-((3S)-1-(tert-butoxycarbonyl)-3-fluoropiperidin-4-yl)acetic acid (CAS 2306259-26-5), molecular formula C12H20FNO4 and molecular weight 261.29 g/mol, is a CATO reference standard with documented purity and traceability.
2-((3S)-1-(tert-butoxycarbonyl)-3-fluoropiperidin-4-yl)acetic acid (C12H20FNO4) 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. 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.
