Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-2-ethynyl-1-iodobenzene.
4-Chloro-2-ethynyl-1-iodobenzene (CAS 2354099-41-3), molecular formula C8H4ClI and molecular weight 262.47 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-2-ethynyl-1-iodobenzene (C8H4ClI) contains chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
