Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.09 g/mol gives 1-(3-Bromo-4-methylphenyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(3-Bromo-4-methylphenyl)ethanol (CAS 65189-93-7), molecular formula C9H11BrO and molecular weight 215.09 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Bromo-4-methylphenyl)ethanol (C9H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1-(3-Bromo-4-methylphenyl)ethanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
