Description

Rubropunctatin CAS NO 514-67-0 is a vibrant orange-red azaphilone pigment, a secondary metabolite primarily produced by fungi of the genus *Monascus*. This compound is of significant commercial and research interest due to its potent biological activities and distinctive color properties. It is a key target for industries focused on natural colorants, pharmaceuticals, and biochemical research. The global market for this high-value specialty chemical includes manufacturers of natural food colorings, nutraceutical developers, and institutions engaged in antimicrobial and anticancer research.

Application

• As a natural food colorant and pigment in fermented food products, providing an alternative to synthetic dyes.
• As a key biochemical standard and reference material for analytical research and quality control in the production of *Monascus* pigments (e.g., Monascus Red).
• In pharmaceutical research for studying its antimicrobial, anti-inflammatory, and potential anticancer properties.
• As an intermediate in organic synthesis for the development of novel azaphilone derivatives with enhanced bioactivity.
• In nutraceutical formulations where *Monascus*-fermented products are used, requiring precise quantification and standardization.
• For academic and industrial R&D in microbiology, mycology, and natural product chemistry.
