Chemical Structure
Description
CATO supplies Methyl 3,5-dimethyl-4-fluorobenzoate (CAS 120512-60-9), a certified reference material (molecular formula C10H11FO2, MW 182.19 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3,5-dimethyl-4-fluorobenzoate (C10H11FO2) 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.
As a certified reference material (CRM), Methyl 3,5-dimethyl-4-fluorobenzoate 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.
