Chemical Structure

<I>Trans</I>-2,5-difluorocinnamic acid CAS 112898-33-6 chemical structure

Description

CATO manufactures <I>Trans</I>-2,5-difluorocinnamic acid 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.

<I>Trans</I>-2,5-difluorocinnamic acid (CAS 112898-33-6) is a high-purity analytical reference standard with the molecular formula C9H12F2O2 and a molecular weight of 190.19 g/mol.

<I>Trans</I>-2,5-difluorocinnamic acid (C9H12F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
