Chemical Structure

2,4,4,4-Tetrachlorobut-2-enal CAS 19429-51-7 chemical structure

Description

As a certified reference material (CRM), 2,4,4,4-Tetrachlorobut-2-enal 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.

2,4,4,4-Tetrachlorobut-2-enal (CAS 19429-51-7), molecular formula C4H2Cl4O and molecular weight 207.87 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4,4,4-Tetrachlorobut-2-enal (C4H2Cl4O) is characterized by a hydroxyl group, an ether linkage, chlorine 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.

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