5-Hydroxy-2-methyl-naphtho[1,2-b]furan-3-carboxylic acid CAS 17112-91-3

Description

The occurrence of 5-Hydroxy-2-methyl-naphtho[1,2-b]furan-3-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Hydroxy-2-methyl-naphtho[1,2-b]furan-3-carboxylic acid (CAS 17112-91-3), molecular formula C14H10O4 and molecular weight 242.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H10O4, 5-Hydroxy-2-methyl-naphtho[1,2-b]furan-3-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
