Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-6,7-dimethoxy-1-naphthaldehyde.
2-Hydroxy-6,7-dimethoxy-1-naphthaldehyde (CAS 92802-59-0), molecular formula C13H12O4 and molecular weight 232.23 g/mol, is a CATO reference standard with documented purity and traceability.
2-Hydroxy-6,7-dimethoxy-1-naphthaldehyde (C13H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 2-Hydroxy-6,7-dimethoxy-1-naphthaldehyde 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.
