CAS 81-54-9

Purpurin

Description:

Purpurin, with the CAS number 81-54-9, is an organic compound belonging to the class of anthraquinones, which are characterized by their aromatic structure and extensive conjugation. It is a red dye that is primarily derived from the madder plant, historically used in textiles. Purpurin exhibits a strong absorption in the visible spectrum, contributing to its vibrant color, and is known for its ability to form complexes with metal ions, which can enhance its color stability and application in various fields. The compound is soluble in organic solvents but has limited solubility in water. Purpurin has been studied for its potential applications in dye-sensitized solar cells, as well as in biochemistry for its fluorescent properties. Additionally, it has shown some biological activity, including antimicrobial properties. However, like many organic dyes, its environmental impact and stability under light exposure are important considerations in its use. Overall, purpurin is a significant compound in both historical and modern contexts, particularly in dye chemistry and materials science.

Controlled Product

CAS: 81-54-9

Applications Purpurin is an anthraquinone derivative and is well known as a colour pigment derived from madder plants. Purpurin was extensively utilized in herbal remedies, in food colouring and dyes for cotton printing. Due to the high antioxidant activity exhibited by anthraquinone compounds, purpurin was determined through studies to possess potential radical scavenging effects. Purprin has also been shown to have inhibitory effects towards serine protease. Dyes and metabolites.

Purpurin is a natural compound that belongs to the group of sodium salts. It has been shown to have antimicrobial activity against many Gram-positive and Gram-negative bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). Purpurin also has antioxidant properties and can be used for the treatment of infectious diseases. The photochemical properties of purpurin have been studied extensively. The matrix effect of purpurin on the cytochrome P450 enzyme system in human serum is well established. Purpurin has been shown to inhibit mitochondrial membrane potential and increase electron transfer resistance in mitochondria from rat liver cells. Purpurin has not been found to be toxic to humans after oral administration, but toxicity studies are still ongoing.
