Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Butoxy-1-chloro-2,4-difluoro-5-methylbenzene (CAS 1881293-68-0), a certified reference material (molecular formula C11H13ClF2O, MW 234.67 g/mol) for analytical method development and quality control.
The molecular framework of 3-Butoxy-1-chloro-2,4-difluoro-5-methylbenzene (C11H13ClF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3-Butoxy-1-chloro-2,4-difluoro-5-methylbenzene 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.
