4-Bromo-5,8-dimethylquinoline CAS 1070879-34-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Bromo-5,8-dimethylquinoline (CAS 1070879-34-3) is a high-purity analytical reference standard with the molecular formula C11H10BrN and a molecular weight of 236.11 g/mol.

Structurally, 4-Bromo-5,8-dimethylquinoline (C11H10BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 236.11 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
