What is Diosmetin CAS 520-34-3?

Diosmetin is an O-methylated flavone also known as luteolin 4'-methyl ether or 5,7,3'-trihydroxy-4'-methoxyflavone. Its CAS number is 520-34-3, EC number is 208-291-8, molecular formula is C16H12O6, and molecular weight is about 300.26.

What does Diosmetin look like and how soluble is it?

It is normally supplied as a yellow crystal powder or light yellow to yellow powder with a melting point around 256-259 C. It is sparingly soluble in water and more soluble in solvents such as DMSO, ethanol, acetonitrile, acetone, chloroform, and dichloromethane.

What is Diosmetin used for?

Diosmetin is primarily supplied for research, analytical reference, laboratory evaluation, and specialty chemical procurement. It is a botanical flavone used as a technical or reference material rather than a finished consumer product.

Which specifications should be checked before ordering Diosmetin?

Confirm appearance, purity or HPLC assay, melting range, water content or loss on drying, residual solvents, and related flavonoid impurities. If the intended use is analytical, confirm whether a reference-standard, analytical-grade, or custom laboratory grade is required.

How should Diosmetin be stored and handled?

Store it in tightly closed, light-protected containers under the temperature conditions specified for the offered grade, which may be ambient or refrigerated. Use suitable PPE, avoid dust generation, and follow the label and local laboratory handling procedures.
