Description

Compared with other compounds in its class, the molecular weight of 246.18 g/mol gives 2-methyl-3-[4-(trifluoromethoxy)phenyl]prop-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-methyl-3-[4-(trifluoromethoxy)phenyl]prop-2-enoic acid (CAS 773121-23-6), molecular formula C11H9F3O3 and molecular weight 246.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-methyl-3-[4-(trifluoromethoxy)phenyl]prop-2-enoic acid (C11H9F3O3) 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).

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), 2-methyl-3-[4-(trifluoromethoxy)phenyl]prop-2-enoic acid 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.
