5-Ethyl-2-hydroxy-3-methoxybenzoic acid CAS 100245-34-9

Description

The occurrence of 5-Ethyl-2-hydroxy-3-methoxybenzoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Ethyl-2-hydroxy-3-methoxybenzoic acid (CAS 100245-34-9) is a high-purity analytical reference standard with the molecular formula C10H12O4 and a molecular weight of 196.20 g/mol.

Based on its molecular formula C10H12O4, 5-Ethyl-2-hydroxy-3-methoxybenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 196.20 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.

As a certified reference material (CRM), 5-Ethyl-2-hydroxy-3-methoxybenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
