Description
CATO manufactures 3-Bromobenzonitrile-2,4,5,6-d4 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.
3-Bromobenzonitrile-2,4,5,6-d4 (CAS 81395-18-8), molecular formula C7D4BrN and molecular weight 186.04 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromobenzonitrile-2,4,5,6-d4 (C7D4BrN) contains deuterium isotope labeling, a nitrile group, bromine 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.
