CAS 1260-17-9
:Carminic acid
Description:
Carminic acid, with the CAS number 1260-17-9, is a natural organic compound primarily derived from the cochineal insect, specifically from the scale of the Dactylopius coccus. It is a red pigment that belongs to the class of anthraquinones and is known for its vibrant color, which is often used in food, cosmetics, and textiles. Carminic acid is soluble in water and alcohol, but insoluble in non-polar solvents, which makes it versatile for various applications. The compound exhibits strong UV-Vis absorption characteristics, contributing to its use as a dye. Additionally, carminic acid has been studied for its potential antioxidant properties. Its stability can be affected by pH and light exposure, which is important for its application in products. As a natural dye, it is often preferred over synthetic alternatives due to its lower toxicity and environmental impact. However, it is important to note that some individuals may have allergic reactions to carminic acid, which should be considered in its use.

CAS:Carminic acid is a natural pigment, which is a red dye obtained from the cochineal insect, Dactylopius coccus. This compound is extracted through the processing of these insects, which are primarily harvested from cacti. The mode of action of carminic acid involves its ability to bind with proteins and metal ions, creating a stable colorant that is resistant to heat and light. This stability makes it particularly valuable in applications requiring long-lasting pigmentation.Formula:C22H20O13Color and Shape:PowderMolecular weight:492.39 g/mol
