Chemical Structure

2,4-Dichloro-3-(3-methylphenyl)propiophenone CAS 898768-04-2 chemical structure

Description

The occurrence of 2,4-Dichloro-3-(3-methylphenyl)propiophenone is closely related to 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.

2,4-Dichloro-3-(3-methylphenyl)propiophenone (CAS 898768-04-2), molecular formula C16H14Cl2O and molecular weight 293.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 2,4-Dichloro-3-(3-methylphenyl)propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2,4-Dichloro-3-(3-methylphenyl)propiophenone 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.
