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

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.

Why is Paracetamol also called Acetaminophen?

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.

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

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.

Is Paracetamol intended for direct consumer use?

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.

How should Paracetamol API be stored and protected during handling?

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.
