Chemical Structure
Description
The occurrence of 4-Bromo-2-chloro-6-(chloromethyl)pyridine is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-chloro-6-(chloromethyl)pyridine (CAS 1393554-93-2), molecular formula C6H4BrCl2N and molecular weight 240.91 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H4BrCl2N, 4-Bromo-2-chloro-6-(chloromethyl)pyridine contains a nitrile group, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-Bromo-2-chloro-6-(chloromethyl)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.
