Methyl 4-({2-[(E)-2-(2,4-dichlorophenyl)ethenyl]-1H-1,3-benzodiazol-1-yl}methyl)benzoate CAS 206982-89-0 chemical structure

Description

The occurrence of Methyl 4-({2-[(E)-2-(2,4-dichlorophenyl)ethenyl]-1H-1,3-benzodiazol-1-yl}methyl)benzoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 4-({2-[(E)-2-(2,4-dichlorophenyl)ethenyl]-1H-1,3-benzodiazol-1-yl}methyl)benzoate (CAS 206982-89-0), molecular formula C24H18Cl2N2O2 and molecular weight 437.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 4-({2-[(E)-2-(2,4-dichlorophenyl)ethenyl]-1H-1,3-benzodiazol-1-yl}methyl)benzoate (C24H18Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 437.32 g/mol, it falls into the moderately-high-molecular-weight range. 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), Methyl 4-({2-[(E)-2-(2,4-dichlorophenyl)ethenyl]-1H-1,3-benzodiazol-1-yl}methyl)benzoate 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.
