Chemical Structure
Description
The occurrence of 7-Methylquinoline-4-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Methylquinoline-4-carboxylic acid (CAS 816448-99-4), a certified reference material (molecular formula C11H9NO2, MW 187.19 g/mol) for analytical method development and quality control.
Structurally, 7-Methylquinoline-4-carboxylic acid (C11H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 187.19 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
