Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 444.36 g/mol gives 4-Trifluoromethylumbelliferyl b-D-Glucuronide Potassium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Trifluoromethylumbelliferyl b-D-Glucuronide Potassium Salt (CAS 143547-78-8) is a high-purity analytical reference standard with the molecular formula C16H12F3O9K and a molecular weight of 444.36 g/mol.
The molecular framework of 4-Trifluoromethylumbelliferyl b-D-Glucuronide Potassium Salt (C16H12F3O9K) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 4-Trifluoromethylumbelliferyl b-D-Glucuronide Potassium Salt 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.
