4-Fluoro-N'-(1-(phenylsulfonyl)piperidin-4-ylidene)benzohydrazide CAS 478248-21-4

Description

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.

4-Fluoro-N'-(1-(phenylsulfonyl)piperidin-4-ylidene)benzohydrazide (CAS 478248-21-4), molecular formula C18H18FN3O3S and molecular weight 375.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Fluoro-N'-(1-(phenylsulfonyl)piperidin-4-ylidene)benzohydrazide (C18H18FN3O3S) is characterized by a steroid core, an amide group, a sulfone 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).

As a certified reference material (CRM), 4-Fluoro-N'-(1-(phenylsulfonyl)piperidin-4-ylidene)benzohydrazide 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.
