Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 229.92 g/mol gives 1,3-Dichloro-5-dichloromethyl-benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Dichloro-5-dichloromethyl-benzene (CAS 56961-85-4) is a high-purity analytical reference standard with the molecular formula C7H4Cl4 and a molecular weight of 229.92 g/mol.
The molecular framework of 1,3-Dichloro-5-dichloromethyl-benzene (C7H4Cl4) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Dichloro-5-dichloromethyl-benzene 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.
