Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.71 g/mol gives 2-[(2-chlorophenyl)methoxy]-5-methylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[(2-chlorophenyl)methoxy]-5-methylbenzoic acid (CAS 1053116-94-1), molecular formula C15H13ClO3 and molecular weight 276.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[(2-chlorophenyl)methoxy]-5-methylbenzoic acid (C15H13ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
