Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-Bromothiophen-2-yl)-3-chloroquinoxaline.
CATO supplies 2-(5-Bromothiophen-2-yl)-3-chloroquinoxaline (CAS 66078-66-8), a certified reference material (molecular formula C12H6BrClN2S, MW 325.61 g/mol) for analytical method development and quality control.
2-(5-Bromothiophen-2-yl)-3-chloroquinoxaline (C12H6BrClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(5-Bromothiophen-2-yl)-3-chloroquinoxaline 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.
