Chemical Structure
Description
The occurrence of 3-Bromo-2-(ethylsulfanyl)-5-(trifluoromethyl)pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-2-(ethylsulfanyl)-5-(trifluoromethyl)pyridine (CAS 1881290-49-8), molecular formula C8H7BrF3NS and molecular weight 286.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution, 3-Bromo-2-(ethylsulfanyl)-5-(trifluoromethyl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.11 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), 3-Bromo-2-(ethylsulfanyl)-5-(trifluoromethyl)pyridine 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.
