  • Applications

    Maltopentaose (CAS 34620-76-3) is used as a carbohydrate intermediate and building block in starch-derived oligosaccharide chemistry; in industrial formulations it is commonly employed as a bulking agent and as a component of starch-hydrolysis products. It also serves as a substrate for enzymatic assays of amylases and as a reference material for carbohydrate analysis. In pharmaceutical and cosmetic formulations, it may be used as an excipient or carrier and can help adjust moisture retention and formulation texture.
