Amylose triacetate, also known as starch acetate, is a chemical derivative of starch, a polysaccharide composed of glucose units. It is produced by the acetylation of amylose, the linear component of starch, with acetic anhydride, resulting in the formation of acetate ester groups on the hydroxyl groups of the glucose units. This modification enhances the stability, solubility, and film-forming properties of the polymer. Amylose triacetate is used in various applications, including pharmaceuticals as a coating agent for controlled drug release, in the food industry as a stabilizer and thickener, and in the production of biodegradable films and coatings. Its unique properties, such as resistance to water and oils, make it a valuable material in these industries.
The CAS Registry Mumber 9040-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 0 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 9040-62: (6*9)+(5*0)+(4*4)+(3*0)+(2*6)+(1*2)=84 84 % 10 = 4 So 9040-62-4 is a valid CAS Registry Number.
