Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Furo[3,4-b]quinoline-1,3-dione.
CATO supplies Furo[3,4-b]quinoline-1,3-dione (CAS 4945-42-0), a certified reference material (molecular formula C11H5NO3, MW 199.16 g/mol) for analytical method development and quality control.
Structurally, Furo[3,4-b]quinoline-1,3-dione (C11H5NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 199.16 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.
