When sourcing Ibuprofen Powder, it is critical to ensure the product complies with international pharmacopoeia standards such as USP (United States Pharmacopeia), BP (British Pharmacopeia), or EP (European Pharmacopoeia). Key technical parameters include a purity level (assay) of 98.5% to 101.0%, specific melting point ranges (75°C to 78°C), and strict limits on heavy metals (<10ppm) and individual impurities (<0.1%). Buyers should also specify the particle size (mesh size), as micronized powder is often required for specific formulation needs like rapid-release tablets.
