Chemical Structure

Methyl 4-acetyl-2-methoxybenzoate CAS 85865-58-3 chemical structure

Description

The occurrence of Methyl 4-acetyl-2-methoxybenzoate 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.

CATO supplies Methyl 4-acetyl-2-methoxybenzoate (CAS 85865-58-3), a certified reference material (molecular formula C11H12O4, MW 208.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H12O4, Methyl 4-acetyl-2-methoxybenzoate 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 208.21 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.

CATO manufactures Methyl 4-acetyl-2-methoxybenzoate 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.
