Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis(2,2,2-trifluoroethyl) but-2-enedioate.
CATO supplies Bis(2,2,2-trifluoroethyl) but-2-enedioate (CAS 156631-37-7), a certified reference material (molecular formula C8H6F6O4, MW 280.12 g/mol) for analytical method development and quality control.
The molecular framework of Bis(2,2,2-trifluoroethyl) but-2-enedioate (C8H6F6O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Bis(2,2,2-trifluoroethyl) but-2-enedioate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
