Description

The molecular framework of 2206-43-1 4-Methoxyisophthalic acid 4-methoxy sophthalic acid 4-methoxybenzene-1,3-dicarboxylic acid 4-methoxyisophthalic acid 98% 5-methoxy-1,3 dicarboxylic acid 5-methoxy-isophathalic acid p-methoxyisophthalic acid p-methoxysophthalicacid (C9H14O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

2206-43-1 4-Methoxyisophthalic acid 4-methoxy sophthalic acid 4-methoxybenzene-1,3-dicarboxylic acid 4-methoxyisophthalic acid 98% 5-methoxy-1,3 dicarboxylic acid 5-methoxy-isophathalic acid p-methoxyisophthalic acid p-methoxysophthalicacid (CAS 2206-43-1), molecular formula C9H14O5 and molecular weight 202.20 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.

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.
