(2E)-3-(4-tert-Butylphenyl)-1-(2,4-dichlorophenyl)prop-2-en-1-one CAS 444808-24-6

Description

The occurrence of (2E)-3-(4-tert-Butylphenyl)-1-(2,4-dichlorophenyl)prop-2-en-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2E)-3-(4-tert-Butylphenyl)-1-(2,4-dichlorophenyl)prop-2-en-1-one (CAS 444808-24-6) is a high-purity analytical reference standard with the molecular formula C19H18Cl2O and a molecular weight of 333.25 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, (2E)-3-(4-tert-Butylphenyl)-1-(2,4-dichlorophenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (2E)-3-(4-tert-Butylphenyl)-1-(2,4-dichlorophenyl)prop-2-en-1-one 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.
