WebCyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. It is a building block for pharmaceuticals (e.g., mucolytics, analgesics, and bronchodilators ). The amine itself is an effective corrosion inhibitor. http://unifac.ddbst.de/en/EED/AZD/AZD%20Cyclohexane%3BWater.php
