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 1-(Benzenesulfonyl)-4,6-dichloro-3-iodo-1H-pyrrolo[2,3-b]pyridine.
1-(Benzenesulfonyl)-4,6-dichloro-3-iodo-1H-pyrrolo[2,3-b]pyridine (CAS 2055841-50-2), molecular formula C13H7Cl2IN2O2S and molecular weight 453.08 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Benzenesulfonyl)-4,6-dichloro-3-iodo-1H-pyrrolo[2,3-b]pyridine (C13H7Cl2IN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 1-(Benzenesulfonyl)-4,6-dichloro-3-iodo-1H-pyrrolo[2,3-b]pyridine 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.
