Silymarin(CAS: 84604-20-6)

Silymarin (CAS: 84604-20-6) is a complex mixture of flavonolignans. It is typically a yellow to brown powder with a molecular weight of around 1000 Da. Silymarin has poor water solubility but good solubility in ethanol and other organic solvents. It is stable under neutral and slightly acidic conditions but can degrade under basic conditions. It has antioxidant and hepatoprotective properties.

Silymarin can be synthesized through chemical methods, involving the synthesis of silybin from 4,6-di-O-methyltyrosinol and 8-methoxysilybin. Commonly, it involves the use of acetic anhydride and pyridine as reagents, with a yield of approximately 60-70%. The synthesis process is selective and requires precise control of pH and temperature.

Silymarin is widely used in the pharmaceutical industry for its hepatoprotective properties. It is also utilized in the food industry as a natural coloring and antioxidant. Additionally, it has applications in the cosmetic industry for its skin care benefits. Research is ongoing in the development of its use in polymers and sensors.

When handling Silymarin (CAS: 84604-20-6), it is important to wear gloves and goggles to protect against skin and eye contact. Silymarin should be stored in a cool, dry place away from direct sunlight. In case of a spill, use personal protective equipment (PPE) such as gloves and a fume hood. Refer to the Safety Data Sheet (SDS) for detailed information on handling and emergency procedures.
