Chemical Structure
Description
6-Methoxy-2-tetralone (CAS 2672-22-2), molecular formula C11H12O2 and molecular weight 176.21 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methoxy-2-tetralone (C11H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
As a certified reference material (CRM), 6-Methoxy-2-tetralone 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.
