Description

Benzocaine Hydrochloride is a water-soluble hydrochloride salt form of the widely used local anesthetic benzocaine. This compound is valued for its enhanced solubility profile compared to the free base, facilitating formulation in aqueous systems. It is primarily utilized in the pharmaceutical and research sectors where a readily soluble anesthetic agent is required for topical preparations, analytical standards, and biochemical studies.

Application

• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of more complex anesthetic and analgesic drug compounds.
• Topical Anesthetic Formulations: Used in the development of creams, gels, and sprays for temporary relief of pain and itching from minor skin irritations, offering improved water solubility.
• Analytical Reference Standards: Employed as a high-purity standard in quality control laboratories for HPLC, UV, and other analytical methods to identify and quantify benzocaine in products.
• Veterinary Medicine: Incorporated into topical preparations for surface anesthesia in animals during minor procedures or to alleviate discomfort.
• Biochemical Research: Utilized in laboratory studies investigating the mechanism of action of sodium channel blockers and local anesthetics.
• Dental Preparations: A component in some oral gels or pastes designed to numb gum tissue or soothe mouth ulcers.

Quality Control

Our Benzocaine Hydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive testing to ensure identity, purity, and consistency. We can supply material that meets in-house specifications or tailor quality parameters to your project requirements. Certificates of Analysis (COA) documenting key parameters are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). The material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture.
