(E)-1,4-Bis(4-chlorophenyl)but-2-ene-1,4-dione CAS 5465-37-2

Description

The occurrence of (E)-1,4-Bis(4-chlorophenyl)but-2-ene-1,4-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-1,4-Bis(4-chlorophenyl)but-2-ene-1,4-dione (CAS 5465-37-2), molecular formula C16H10Cl2O2 and molecular weight 305.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, (E)-1,4-Bis(4-chlorophenyl)but-2-ene-1,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), (E)-1,4-Bis(4-chlorophenyl)but-2-ene-1,4-dione 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.
