5-[(3S,4R)-1-[(tert-butoxy)carbonyl]-3-{[(tert-butyldimethylsilyl)oxy]methyl}piperidin-4-yl]-2-fluorobenzoic acid CAS 2055991-10-9 chemical structure

Description

5-[(3S,4R)-1-[(tert-butoxy)carbonyl]-3-{[(tert-butyldimethylsilyl)oxy]methyl}piperidin-4-yl]-2-fluorobenzoic acid (CAS 2055991-10-9), molecular formula C24H38FNO5Si and molecular weight 467.65 g/mol, is a CATO reference standard with documented purity and traceability.

5-[(3S,4R)-1-[(tert-butoxy)carbonyl]-3-{[(tert-butyldimethylsilyl)oxy]methyl}piperidin-4-yl]-2-fluorobenzoic acid (C24H38FNO5Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-[(3S,4R)-1-[(tert-butoxy)carbonyl]-3-{[(tert-butyldimethylsilyl)oxy]methyl}piperidin-4-yl]-2-fluorobenzoic 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.
