Description

CATO manufactures 5H-dibenzo[a,d][7]annulen-5-one oxime 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.

5H-dibenzo[a,d][7]annulen-5-one oxime (CAS 1021-91-6), molecular formula C15H11NO and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.

5H-dibenzo[a,d][7]annulen-5-one oxime (C15H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
