Chemical Structure
Description
2-Bromo-1-isopropyl-3-methoxybenzene (CAS 820258-24-0), molecular formula C10H13BrO and molecular weight 229.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-1-isopropyl-3-methoxybenzene (C10H13BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
