Chemical Structure
Description
The occurrence of 3-Bromo-2-(propylsulfanyl)-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-(propylsulfanyl)-5-(trifluoromethyl)pyridine (CAS 1881293-26-0), molecular formula C9H9BrF3NS and molecular weight 300.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Bromo-2-(propylsulfanyl)-5-(trifluoromethyl)pyridine (C9H9BrF3NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 300.14 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
