Halometasone is a synthetic glucocorticoid and active pharmaceutical ingredient (API) used in topical formulations to treat inflammatory skin conditions such as eczema, psoriasis, dermatitis, and other dermatoses. It exerts potent anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2 and reducing the synthesis of prostaglandins and leukotrienes, thereby alleviating redness, swelling, itching, and discomfort. This product is supplied as a high-purity (97.5-100% by HPLC) white crystalline powder for use in pharmaceutical manufacturing, research, or formulation development. It is not intended for direct consumer application; formulated products should be used under medical supervision to avoid side effects like skin thinning, irritation, or systemic absorption with prolonged use.
