Description
As a certified reference material (CRM), (R)-2-Bromo-1-(naphthalen-1-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.
(R)-2-Bromo-1-(naphthalen-1-yl)ethan-1-ol (CAS 220954-08-5), 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, (R)-2-Bromo-1-(naphthalen-1-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. 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.
