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 5-fluoro-2-(1H-1,2,4-triazol-5-ylthio)aniline.
5-fluoro-2-(1H-1,2,4-triazol-5-ylthio)aniline (CAS 1019538-54-5), molecular formula C8H7FN4S and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.
5-fluoro-2-(1H-1,2,4-triazol-5-ylthio)aniline (C8H7FN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. 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.
