Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.31 g/mol gives 2-[(6-Methoxy-2-naphthalenyl)carbonyl]benzoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[(6-Methoxy-2-naphthalenyl)carbonyl]benzoic Acid (CAS 71964-75-5), molecular formula C19H14O4 and molecular weight 306.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[(6-Methoxy-2-naphthalenyl)carbonyl]benzoic Acid (C19H14O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
