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 4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole.
CATO supplies 4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole (CAS 18557-22-7), a certified reference material (molecular formula C10H4Br2N2S, MW 344.03 g/mol) for analytical method development and quality control.
4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole (C10H4Br2N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 4,9-Dibromonaphtho[2,3-c][1,2,5]thiadiazole 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.
