Chemical Structure
Description
As a certified reference material (CRM), (3-Bromo-4-fluorophenyl)(cyclopentyl)methanol 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.
(3-Bromo-4-fluorophenyl)(cyclopentyl)methanol (CAS 1341403-95-9), molecular formula C12H14BrFO and molecular weight 273.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3-Bromo-4-fluorophenyl)(cyclopentyl)methanol (C12H14BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 273.14 g/mol, it falls into the medium-molecular-weight range. 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.
