(1-Acetyl-2,2,6,6-tetramethylpiperidin-4-ylidene)amino 4-fluorobenzoate (CAS 478079-93-5) is a high-purity analytical reference standard with the molecular formula C18H23FN2O3 and a molecular weight of 334.39 g/mol.
The molecular framework of (1-Acetyl-2,2,6,6-tetramethylpiperidin-4-ylidene)amino 4-fluorobenzoate (C18H23FN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (1-Acetyl-2,2,6,6-tetramethylpiperidin-4-ylidene)amino 4-fluorobenzoate 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.
