Chemical Structure
Description
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.
3,5-Dibromo-2-chloro-4,6-dimethylpyridine (CAS 915946-47-3), molecular formula C7H6Br2ClN and molecular weight 299.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/bromine substitution, an aromatic ring system, 3,5-Dibromo-2-chloro-4,6-dimethylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
