Send us your requirements.
Each product ships with a Certificate of Analysis (COA) covering HPLC purity, melting point (where applicable), and physical specification. SDS and TDS are available on request. For regulated-market imports, we provide REACH compliance statements, ICH Q3D elemental impurity data, and residual solvent testing per ICH Q3C.
Our hair dye intermediates — including p-Phenylenediamine, Resorcinol, Aminoanisole derivatives, and HC colorants — are supplied with REACH registration data and impurity profiles. Compliance with EU Cosmetics Regulation (EC 1223/2009) is the responsibility of the formulator; we provide full analytical data to support their safety assessments.
Standard MOQ is 1–25kg depending on the product. Common industrial intermediates (Aniline, Acetic Anhydride, Resorcinol) are available in drum quantities. Specialty or high-value intermediates can be supplied in smaller quantities from 100g. Sample quantities are available for new customers subject to NDA.
Yes — Candesartan (CAS 139481-59-7) and Olmesartan (CAS 144689-63-4) are available from GMP-certified Chinese manufacturers. These are API-grade materials supplied with full batch documentation.
