3-Methoxy-9H-xanthen-9-one 3-Methoxyxanthone 3-methoxyxanthen-9-one 3722-52-9 9H-Xanthen-9-one, 3-methoxy- NSC37335 Xanthen-9-one, 3-methoxy- CAS 3722-52-9 chemical structure

Description

The molecular framework of 3-Methoxy-9H-xanthen-9-one 3-Methoxyxanthone 3-methoxyxanthen-9-one 3722-52-9 9H-Xanthen-9-one, 3-methoxy- NSC37335 Xanthen-9-one, 3-methoxy- (C14H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

3-Methoxy-9H-xanthen-9-one 3-Methoxyxanthone 3-methoxyxanthen-9-one 3722-52-9 9H-Xanthen-9-one, 3-methoxy- NSC37335 Xanthen-9-one, 3-methoxy- (CAS 3722-52-9), molecular formula C14H10O3 and molecular weight 226.23 g/mol, is a CATO reference standard with documented purity and traceability.

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-Methoxy-9H-xanthen-9-one 3-Methoxyxanthone 3-methoxyxanthen-9-one 3722-52-9 9H-Xanthen-9-one, 3-methoxy- NSC37335 Xanthen-9-one, 3-methoxy- 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.
