    Product Characteristics

    Acetylsalicylic acid is a stable, odorless crystalline solid under dry storage conditions. It is slightly soluble in water and soluble in ethanol, ethyl ether, chloroform, sodium hydroxide solution, and sodium carbonate solution. In the presence of moisture, acetylsalicylic acid can gradually hydrolyze into salicylic acid and acetic acid.

    Its established pharmaceutical properties make aspirin / acetylsalicylic acid an important active pharmaceutical ingredient (API) for a range of healthcare and pharmaceutical formulations.

    Applications

    Acetylsalicylic acid is commonly used as a pharmaceutical active ingredient in formulations associated with:

    • Analgesic applications – supporting the management of pain such as headache and muscle pain.

    • Antipyretic applications – used in formulations intended to reduce fever.

    • Anti-inflammatory applications – used in pharmaceutical preparations requiring anti-inflammatory activity.

    • Antiplatelet applications – utilized in cardiovascular and cerebrovascular pharmaceutical formulations where platelet aggregation inhibition is indicated.

    • Research and pharmaceutical manufacturing – suitable as a raw material for qualified manufacturers, formulation developers, laboratories, and research organizations.

    For pharmaceutical use, final applications, dosage forms, indications, and regulatory requirements should be determined by the responsible qualified professionals and applicable local regulations.
