Carminic Acid 50% CAS: 1260-17-9 | MF: C22H20O13 | MW: 492.39S10043, Part Number S10043, Buy Histological Stains & Dyes for Histology, Cytology, Microbiology, Hematology & Biology Lab from TriStains at Chemical World.
.In its concentrated form (50%), carminic acid may appear as a red to purple powder or liquid. Carminic acid is a glucosidal hydroxyanthrapurin compound. Additionally, the percentage (e.g., 50%) indicates the concentration of the carminic acid solution, and different concentrations may be used depending on the application. Carminic acid is a natural red pigment derived from the scale insect Dactylopius coccus, commonly known as cochineal. It is a water-soluble compound responsible for the vibrant red color associated with cochineal extract. Carminic acid, due to its red color, may be employed as a biological stain in certain applications.
