(R)-2-Bromo-4-methylpentanoic acid CAS 42990-28-3

Description

Compared with other compounds in its class, the molecular weight of 195.05 g/mol gives (R)-2-Bromo-4-methylpentanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-2-Bromo-4-methylpentanoic acid (CAS 42990-28-3) is a high-purity analytical reference standard with the molecular formula C6H11BrO2 and a molecular weight of 195.05 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (R)-2-Bromo-4-methylpentanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
