Chemical Structure
Description
(1R)-2-Bromo-1-(naphthalen-2-yl)ethan-1-ol (CAS 85554-14-9), molecular formula C12H11BrO and molecular weight 251.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, (1R)-2-Bromo-1-(naphthalen-2-yl)ethan-1-ol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (1R)-2-Bromo-1-(naphthalen-2-yl)ethan-1-ol 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.
