Compared with other compounds in its class, the molecular weight of 218.10 g/mol gives 1,5-Dichloro-2-isothiocyanato-3-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,5-Dichloro-2-isothiocyanato-3-methylbenzene (CAS 306935-83-1) is a high-purity analytical reference standard with the molecular formula C8H5Cl2NS and a molecular weight of 218.10 g/mol.
The molecular framework of 1,5-Dichloro-2-isothiocyanato-3-methylbenzene (C8H5Cl2NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1,5-Dichloro-2-isothiocyanato-3-methylbenzene 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.
