Curcumin is a naturally occurring polyphenolic compound known for its anti-inflammatory and antioxidant properties, widely used in dietary supplements, pharmaceuticals, and research. It is used as a food colorant and flavoring, a dye for textiles, oils and waxes, a reagent for boron detection, and an acid-base indicator. It is available in high purity with a molecular weight of 368.39 g/mol, a CAS number of 458-37-7, and a molecular formula of [HOC6H3(OCH3)CH=CHCO]2CH2. Stored at ambient temperatures, it carries a warning signal word due to potential irritant properties.
