FAQ - Technical & Supply Chain

  • Q:

    What is Paracetamol CAS 103-90-2 used for?

    A: It is a pharmaceutical-grade active ingredient used to formulate analgesic and antipyretic medicines. Typical dosage forms include tablets, capsules, and oral suspensions prepared by licensed pharmaceutical manufacturers.
  • Q:

    Why is Paracetamol also called Acetaminophen?

    A: Paracetamol and Acetaminophen are the same active substance, N-acetyl-p-aminophenol, identified by CAS 103-90-2. The two names reflect different international nomenclature rather than different chemical grades or molecular structures.
  • Q:

    What is the typical supply form of this pharmaceutical-grade API?

    A: It is normally supplied as a white crystalline powder suitable for formulation development and manufacturing. Direct-compression grades may also be available with controlled particle size and flow properties for tablet production.
  • Q:

    Is Paracetamol intended for direct consumer use?

    A: No. This product is supplied as a raw pharmaceutical material for processing by qualified manufacturers and formulation facilities, not as a finished dosage form for direct consumer administration.
  • Q:

    How should Paracetamol API be stored and protected during handling?

    A: Store it in tightly sealed, moisture-resistant containers in a cool, dry, well-ventilated area away from direct sunlight and heat. Keep the original packaging closed between uses and follow appropriate pharmaceutical handling procedures.
