Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 296.23 g/mol gives trans-Coutaric acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies trans-Coutaric acid (CAS 27174-07-8), a certified reference material (molecular formula C13H12O8, MW 296.23 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, trans-Coutaric acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
