Chemical Structure
Description
3-Butoxy-6-hydroxy-9H-xanthen-9-one (CAS 164660-81-5), molecular formula C17H16O4 and molecular weight 284.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Butoxy-6-hydroxy-9H-xanthen-9-one (C17H16O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
As a certified reference material (CRM), 3-Butoxy-6-hydroxy-9H-xanthen-9-one 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.
