Methyl 3-bromo-4-cyclopropylbenzoate CAS 1131615-05-8

Description

Compared with other compounds in its class, the molecular weight of 255.11 g/mol gives Methyl 3-bromo-4-cyclopropylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 3-bromo-4-cyclopropylbenzoate (CAS 1131615-05-8) is a high-purity analytical reference standard with the molecular formula C11H11BrO2 and a molecular weight of 255.11 g/mol.

Based on its molecular formula C11H11BrO2, Methyl 3-bromo-4-cyclopropylbenzoate 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 255.11 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.

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.
