Description

Benzonatate CAS NO 32760-16-0 is a non-narcotic antitussive agent, chemically classified as a peripherally acting sodium channel blocker. This compound is critical for providing effective cough suppression without the central nervous system side effects associated with opioid derivatives. It is primarily required by pharmaceutical manufacturers and research institutions for the formulation of prescription cough medications and advanced respiratory therapeutics.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of prescription antitussive (cough suppressant) medications.
• Respiratory Therapeutics: Used in clinical research and development of novel treatments for chronic cough and related respiratory conditions.
• Drug Formulation: Serves as a key intermediate or final API in solid dosage forms such as capsules and softgels.
• Clinical Research: Utilized in pharmacological studies investigating peripheral cough reflex mechanisms.
• Reference Standard: Sourced by analytical laboratories for use as a high-purity standard in quality control (QC) and method development.
• Veterinary Medicine: Potential application in developing cough suppressants for animal health.

Quality Control

Our Benzonatate is manufactured and tested under strict quality management systems. We ensure compliance with relevant pharmacopeial standards, including USP monographs where applicable. Every batch undergoes comprehensive analytical testing for identity, purity, and potency. Certificates of Analysis (COA) documenting all test results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), the container should be kept sealed under an inert gas blanket after opening to maintain product integrity. Keep away from heat and incompatible materials.
