1-(bromomethyl)-4-methoxy-2-methylbenzene CAS 52289-56-2

Description

The occurrence of 1-(bromomethyl)-4-methoxy-2-methylbenzene is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(bromomethyl)-4-methoxy-2-methylbenzene (CAS 52289-56-2), molecular formula C9H11BrO and molecular weight 215.09 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(bromomethyl)-4-methoxy-2-methylbenzene (C9H11BrO) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
