Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-1-(4-Fluorophenyl)ethanol.
(R)-1-(4-Fluorophenyl)ethanol (CAS 101219-68-5) is a high-purity analytical reference standard with the molecular formula C8H9FO and a molecular weight of 140.15 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (R)-1-(4-Fluorophenyl)ethanol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (R)-1-(4-Fluorophenyl)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.
