Tranexamic acid

Tranexamic acid (CAS 1197-18-8) is a synthetic lysine derivative known by the abbreviations AMCA, AMCHA, and the trade designation HAKU. It carries no E-code designation. Supplied as a white crystalline powder under HS code 29224999, it is classified as a pharmaceutical intermediate with the molecular formula C8H15NO2.

In pharmaceutical manufacturing, tranexamic acid functions as an antifibrinolytic agent, blocking plasminogen binding sites to inhibit fibrin breakdown and reduce bleeding in surgical and haemostatic drug formulations. In cosmetic formulations, it suppresses melanin synthesis by interrupting UV-induced plasminogen activation in keratinocytes, making it a functional active in skin-tone-correcting products.

Tranexamic acid is available in pharmaceutical-grade form meeting Ph.Eur. specifications, supporting use in regulated drug manufacturing across the EU. The substance is subject to REACH registration requirements. Procurement teams should confirm grade suitability, documentation packages, and packaging formats directly with our supply team.
