Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,5-Difluoro-3-ethoxy-2-nitrobenzene.
1,5-Difluoro-3-ethoxy-2-nitrobenzene (CAS 1807178-03-5), molecular formula C8H7F2NO3 and molecular weight 203.14 g/mol, is a CATO reference standard with documented purity and traceability.
1,5-Difluoro-3-ethoxy-2-nitrobenzene (C8H7F2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 1,5-Difluoro-3-ethoxy-2-nitrobenzene 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.
