Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 140.15 g/mol gives (4-Fluoro-3-methylphenyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-Fluoro-3-methylphenyl)methanol (CAS 261951-66-0) is a high-purity analytical reference standard with the molecular formula C8H9FO and a molecular weight of 140.15 g/mol.
The molecular framework of (4-Fluoro-3-methylphenyl)methanol (C8H9FO) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4-Fluoro-3-methylphenyl)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.
