Chemical Structure
Description
The occurrence of 5-Bromo-6-ethoxy-2-methylquinoline-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-6-ethoxy-2-methylquinoline-4-carboxylic acid (CAS 89267-28-7) is a high-purity analytical reference standard with the molecular formula C13H12BrNO3 and a molecular weight of 310.14 g/mol.
Structurally, 5-Bromo-6-ethoxy-2-methylquinoline-4-carboxylic acid (C13H12BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 310.14 g/mol, it falls into the moderately-high-molecular-weight range. 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.
