Chemical Structure

2,3-dichloro-5H,7H-furo[3,4-b]pyridin-5-one CAS 1803589-33-4 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 2,3-dichloro-5H,7H-furo[3,4-b]pyridin-5-one.

2,3-dichloro-5H,7H-furo[3,4-b]pyridin-5-one (CAS 1803589-33-4), molecular formula C7H3Cl2NO2 and molecular weight 204.01 g/mol, is a CATO reference standard with documented purity and traceability.

2,3-dichloro-5H,7H-furo[3,4-b]pyridin-5-one (C7H3Cl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 2,3-dichloro-5H,7H-furo[3,4-b]pyridin-5-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
