5-Methoxy-2-naphthoic acid CAS 5043-31-2

Description

Compared with other compounds in its class, the molecular weight of 202.21 g/mol gives 5-Methoxy-2-naphthoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Methoxy-2-naphthoic acid (CAS 5043-31-2), a certified reference material (molecular formula C12H10O3, MW 202.21 g/mol) for analytical method development and quality control.

Structurally, 5-Methoxy-2-naphthoic acid (C12H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 202.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 5-Methoxy-2-naphthoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
