Chemical Structure

2-Bromo-6-chloro-4-fluorophenyl isothiocyanate CAS 1000577-54-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 266.52 g/mol gives 2-Bromo-6-chloro-4-fluorophenyl isothiocyanate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-6-chloro-4-fluorophenyl isothiocyanate (CAS 1000577-54-7) is a high-purity analytical reference standard with the molecular formula C7H2BrClFNS and a molecular weight of 266.52 g/mol.

Owing to a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system, 2-Bromo-6-chloro-4-fluorophenyl isothiocyanate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-Bromo-6-chloro-4-fluorophenyl isothiocyanate 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.
