Methyl 4-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4-oxobutanoate CAS 344280-62-2

Description

The occurrence of Methyl 4-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4-oxobutanoate 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.

Methyl 4-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4-oxobutanoate (CAS 344280-62-2), molecular formula C17H13Cl3O3 and molecular weight 371.64 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 4-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4-oxobutanoate (C17H13Cl3O3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 371.64 g/mol, it falls into the moderately-high-molecular-weight range. 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), Methyl 4-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-4-oxobutanoate 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.
