Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dibromo-3-phenylpyridine.
2,6-Dibromo-3-phenylpyridine (CAS 102249-44-5) is a high-purity analytical reference standard with the molecular formula C11H7Br2N and a molecular weight of 312.99 g/mol.
2,6-Dibromo-3-phenylpyridine (C11H7Br2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
