Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.77 g/mol gives 3'-Hydroxyflavone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3'-Hydroxyflavone (CAS 70460-18-3), molecular formula C17H16ClNO and molecular weight 285.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3'-Hydroxyflavone (C17H16ClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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), 3'-Hydroxyflavone 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.
