Description
CATO manufactures 2-Butoxy-4-fluoro-5-methylphenol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2-Butoxy-4-fluoro-5-methylphenol (CAS 1881328-52-4), a certified reference material (molecular formula C11H15FO2, MW 198.23 g/mol) for analytical method development and quality control.
The molecular framework of 2-Butoxy-4-fluoro-5-methylphenol (C11H15FO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
