The Acetylsalicylic Acid (ASA) by Dinâmica, available at LojaLab, is the acetyl ester of salicylic acid supplied as a reagent for research, education, development and quality control. Its structure contains a carboxylic-acid group and an acetoxy group, supporting studies of acidity, ester hydrolysis, spectroscopic identification and methods for determining ASA and salicylate. The container should therefore remain tightly closed and preparation should account for stability and holding time.
