Chemical Structure
Description
The occurrence of 2,5-Dichlorobenzothioamide is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Dichlorobenzothioamide (CAS 69622-81-7), molecular formula C7H5Cl2NS and molecular weight 206.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,5-Dichlorobenzothioamide (C7H5Cl2NS) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2,5-Dichlorobenzothioamide 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.
