Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-Dibromo-3-chloro-5-(chloromethyl)pyridine (CAS 1823897-35-3), molecular formula C6H3Br2Cl2N and molecular weight 319.81 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,6-Dibromo-3-chloro-5-(chloromethyl)pyridine (C6H3Br2Cl2N) contains a nitrile group, chlorine/bromine substitution, an aromatic ring system. 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 319.81 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).
CATO manufactures 2,6-Dibromo-3-chloro-5-(chloromethyl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
