Overview

(Z)-octadec-9-en-1-amine (CAS 112-90-3) is an unsaturated aliphatic primary amine with a long carbon chain and oleic acid-derived structure. This long-chain fatty amine represents an important class of nitrogen-containing surfactants widely utilized across various industrial applications. The compound features an 18-carbon chain with a cis double bond at the 9th position, derived from oleic acid through amination processes. Its molecular formula C18H37N and molecular weight of 267.5 g/mol reflect its substantial hydrophobic character combined with the hydrophilic amino functionality, making it an effective surface-active agent. The substance presents significant safety considerations requiring careful handling protocols. Classified under multiple hazard categories including corrosive to skin (Skin Corr. 1B), acute toxicity (Acute Tox. 4), and aquatic toxicity (Aquatic Acute 1, Aquatic Chronic 1), it demands appropriate personal protective equipment and containment measures. The ADR classification as Class 8 (corrosive substances) underscores its transport requirements, while GHS pictograms GHS05, GHS07, GHS08, and GHS09 indicate the range of hazards from corrosion to environmental impact. Primary industrial applications include its use as a flotation collector in mineral processing, particularly for phosphate and silicate minerals, where its surfactant properties enable selective separation. The compound also serves as an intermediate in the production of quaternary ammonium compounds and finds application in corrosion inhibitor formulations. Unlike more complex compounds such as tributyl(tetradecyl)phosphanium tetrafluoroborate, this primary amine offers straightforward reactivity for further chemical modifications. OYSI maintains reliable supply chains for (Z)-octadec-9-en-1-amine to support European industrial operations requiring this specialized fatty amine surfactant.
