Description

Racephedrine CAS NO 90-81-3 is a synthetic sympathomimetic amine, chemically known as (±)-ephedrine. This versatile chiral compound is a critical intermediate and active pharmaceutical ingredient (API) in the synthesis of numerous therapeutic agents. It is essential for manufacturers in the pharmaceutical, research, and fine chemical sectors requiring a reliable, high-purity building block for drug development and production.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of decongestants, bronchodilators, and central nervous system stimulants.
• Active Pharmaceutical Ingredient (API): Used in the formulation of medications for the treatment of asthma, nasal congestion, and hypotension.
• Chemical Synthesis: Serves as a chiral building block for producing more complex molecules in medicinal and organic chemistry.
• Research & Development: Utilized in biochemical research and pharmacological studies as a reference standard and for mechanism-of-action investigations.
• Veterinary Pharmaceuticals: Employed in formulations for animal healthcare, particularly for respiratory conditions.
