Chemical Structure
Description
CATO supplies 35975-57-6 8-Bromo-4-hydroxy-quinoline-3-carboxylic acid ethyl ester BB 0222297 (CAS 35975-57-6), a certified reference material (molecular formula C12H20BrNO3, MW 306.20 g/mol) for analytical method development and quality control.
Structurally, 35975-57-6 8-Bromo-4-hydroxy-quinoline-3-carboxylic acid ethyl ester BB 0222297 (C12H20BrNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 306.20 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
