Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.23 g/mol gives Caftaric Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Caftaric Acid (CAS 67879-58-7), molecular formula C13H12O9 and molecular weight 312.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H12O9, Caftaric Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
