Chemical Structure
Description
The occurrence of Methyl 4-Bromo-2-chloro-6-methylbenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 4-Bromo-2-chloro-6-methylbenzoate (CAS 877149-10-5) is a high-purity analytical reference standard with the molecular formula C9H8BrClO2 and a molecular weight of 263.52 g/mol.
Based on its molecular formula C9H8BrClO2, Methyl 4-Bromo-2-chloro-6-methylbenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
