Description

Cromoglicic Acid CAS NO 16110-51-3 is a synthetic organic compound belonging to the chromone class, widely recognized for its mast cell stabilizing properties. This active pharmaceutical ingredient (API) is critical for developing prophylactic treatments for allergic and inflammatory conditions. It is primarily sought by pharmaceutical manufacturers and research institutions engaged in the formulation of ophthalmic solutions, nasal sprays, and inhalation products.

Application

• Pharmaceutical API: Core ingredient in mast cell stabilizer medications for asthma, allergic rhinitis, and allergic conjunctivitis.
• Ophthalmic Solutions: Used in eye drops for the prevention and treatment of allergic conjunctivitis (e.g., vernal keratoconjunctivitis).
• Nasal Sprays: Formulated for the prophylactic management of seasonal and perennial allergic rhinitis.
• Inhalation Products: Key component in dry powder inhalers (DPIs) and nebulizer solutions for controlling asthma symptoms.
• Research & Development: Utilized in biochemical research to study mast cell degranulation and inflammatory pathways.
• Veterinary Medicine: Applied in formulations for managing allergic respiratory conditions in animals.
