3,4-Dichlorobenzotrichloride CAS 13014-24-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4-Dichlorobenzotrichloride (CAS 13014-24-9), molecular formula C7H3Cl5 and molecular weight 264.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dichlorobenzotrichloride (C7H3Cl5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3,4-Dichlorobenzotrichloride 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.
