Diethyl cromoglycate（Cat No.:R060319）is a synthetic chromone derivative known for its anti-allergic and mast cell-stabilizing properties. It is commonly used in the treatment of asthma, allergic rhinitis, and conjunctivitis by preventing the release of histamine and other inflammatory mediators from sensitized mast cells. Structurally, it contains two ethyl ester groups attached to a cromoglycic acid backbone, enhancing its lipophilicity and therapeutic application via inhalation or topical routes. Diethyl cromoglycate is valued for its low systemic absorption and favorable safety profile, making it suitable for long-term use in managing chronic allergic conditions.
