CAS 9047-50-1

Dialdehyde starch

Description:

Dialdehyde starch, with the CAS number 9047-50-1, is a modified form of starch that has been chemically altered to introduce aldehyde groups. This modification enhances its reactivity and solubility compared to native starch. Dialdehyde starch is typically produced through the oxidation of starch using agents such as sodium periodate, which introduces aldehyde functional groups along the starch polymer chain. This modification imparts unique properties, making it useful in various applications, including as a biodegradable thickening agent, a stabilizer in food products, and in the pharmaceutical industry for drug delivery systems. The presence of aldehyde groups allows for cross-linking with proteins and other polymers, enhancing its utility in forming gels and films. Additionally, dialdehyde starch exhibits good compatibility with other ingredients, making it valuable in formulations requiring specific textural or rheological properties. Its biodegradability and non-toxic nature further contribute to its appeal in sustainable product development.

Polydialdehyde starch (Polymeric dialdehyde)

CAS: 9047-50-1

Polydialdehyde starch is a cross-linking agent that is used to form hydrophobic polymers, which are prodrugs. It is a polymer of dialdehydes and can be used as an additive for restenosis prevention. Polydialdehyde starch has been shown to reduce platelet adhesion and aggregation in vitro and in vivo. The mechanism of action may be related to the ability of polydialdehyde starch to bind collagen and promote its degradation by hydrolysis. This also results in an increase in the rate of dilation of blood vessels, which may contribute to the antiplatelet effect. Polydialdehyde starch has been shown to be biodegradable, with a half-life of about two weeks in vivo after injection into rats.
