Description

Compared with other compounds in its class, the molecular weight of 273.26 g/mol gives (E)-4-((4-((difluoromethyl)thio)phenyl)amino)-4-oxobut-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-4-((4-((difluoromethyl)thio)phenyl)amino)-4-oxobut-2-enoic acid (CAS 301313-36-0), molecular formula C11H9F2NO3S and molecular weight 273.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-((4-((difluoromethyl)thio)phenyl)amino)-4-oxobut-2-enoic acid (C11H9F2NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (E)-4-((4-((difluoromethyl)thio)phenyl)amino)-4-oxobut-2-enoic 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.
