2-(6-Methoxy-1-oxo-3,4-dihydronaphthalen-2(1H)-ylidene)acetic acid CAS 13587-70-7

Description

2-(6-Methoxy-1-oxo-3,4-dihydronaphthalen-2(1H)-ylidene)acetic acid (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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-(6-Methoxy-1-oxo-3,4-dihydronaphthalen-2(1H)-ylidene)acetic acid (CAS 13587-70-7), molecular formula C13H12O4 and molecular weight 232.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.
