Description

Dicaine CAS NO 3772-42-7 is a pharmaceutical-grade local anesthetic compound, chemically known as tetracaine hydrochloride. This high-purity active pharmaceutical ingredient (API) is critical for ensuring the efficacy and safety of topical and injectable anesthetic formulations. It is primarily required by manufacturers in the pharmaceutical, medical device, and research sectors for producing ophthalmic solutions, topical creams, and specialized medical preparations.

Application

• Pharmaceutical Manufacturing: Primary active ingredient in topical anesthetic creams, ointments, and gels.
• Ophthalmic Solutions: Key component in eye drops and solutions used for local anesthesia during eye examinations and minor procedures.
• Injectable Anesthetics: Used in spinal and regional anesthesia formulations for surgical and diagnostic procedures.
• Medical Device Coatings: Incorporated into coatings for devices like endotracheal tubes or catheters to reduce patient discomfort.
• Veterinary Medicine: Used in anesthetic preparations for animal healthcare.
• Research & Development: Serves as a reference standard and key material in pharmacological and neuroscientific research.
