Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Bromo-3,4-dimethoxyphenyl)acetic acid.
2-(2-Bromo-3,4-dimethoxyphenyl)acetic acid (CAS 63856-83-7) is a high-purity analytical reference standard with the molecular formula C10H11BrO4 and a molecular weight of 275.10 g/mol.
Based on its molecular formula C10H11BrO4, 2-(2-Bromo-3,4-dimethoxyphenyl)acetic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.10 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
