Description
As a certified reference material (CRM), 2-Hydroxy-5,6-dimethoxy-1-naphthaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-Hydroxy-5,6-dimethoxy-1-naphthaldehyde (CAS 92802-56-7), a certified reference material (molecular formula C13H12O4, MW 232.23 g/mol) for analytical method development and quality control.
2-Hydroxy-5,6-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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
