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.

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.

Product Description

Diosmetin CAS 520-34-3 is an O-methylated flavone with the molecular formula C16H12O6 and EINECS 208-291-8.

Synonyms: Diosmetol; Luteolin 4′-methyl ether; 5,7,3′-Trihydroxy-4′-methoxyflavone.

CAS: 520-34-3.

Molecular formula: C16H12O6.

It is normally supplied as a yellow crystal powder or light yellow to yellow powder with a molecular weight of about 300.26.

It is also known as luteolin 4′-methyl ether or 5,7,3′-trihydroxy-4′-methoxyflavone.

Diosmetin is sparingly soluble in water and more soluble in solvents such as DMSO, ethanol, acetonitrile, acetone, chloroform, and dichloromethane.

It 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.

In analytical work it is used as a reference material where purity, HPLC assay, and related flavonoid impurities matter.

In research and laboratory evaluation it is used depending on the offered grade and intended application.

It is also used in specialty chemical procurement subject to specification and compliance review.

Store in tightly closed, light-protected containers under the temperature conditions specified for the offered grade.

Avoid dust generation and use suitable PPE.

Confirm the offered package, net weight, lot traceability, and transport requirements before dispatch, and follow the current SDS.

Every batch is checked for appearance, purity or HPLC assay, melting range, water content or loss on drying, residual solvents, and related flavonoid impurities, with COA/TDS/SDS supplied per grade.

Confirm appearance, purity, melting range, residual solvents, packaging, and grade as required.
