Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Tembotrione-4,6-dihydroxy (CAS 912654-91-2) is a high-purity analytical reference standard with the molecular formula C17H16ClF3O8S and a molecular weight of 472.82 g/mol.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Tembotrione-4,6-dihydroxy is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Tembotrione-4,6-dihydroxy 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.
