Description
Ibuprofen (CAS 15687-27-1) is a propionic acid derivative classified under organic acids, also known by trade names Brufen, Motrin, and Nurofen, and referenced in technical literature as IP 82, U-18573, and RD 13621. It carries no E-code designation and is identified under EC number 239-784-6 with the molecular formula C13H18O2.
In pharmaceutical formulations, ibuprofen functions as an active analgesic and anti-inflammatory agent by inhibiting cyclooxygenase enzymes, reducing prostaglandin synthesis. In personal care applications, it serves as a skin conditioner and antioxidant stabilizer, helping to protect formulations against oxidative degradation while supporting dermal compatibility.
Ibuprofen is supplied as a crystalline powder meeting Ph.Eur. and USP pharmacopoeial standards, with REACH-compliant documentation available for EU procurement. It is classified under HS code 29163920 and is available in pharmaceutical and technical grades, typically packaged in sealed drums or fibre containers to maintain stability.
