Overview

4-cyclododecyl-2,6-dimethylmorpholine (CAS 1593-77-7) is a specialized morpholine derivative with significant industrial applications and notable safety considerations. This organic compound represents a sophisticated morpholine-based chemical featuring a cyclododecyl substituent and two methyl groups positioned at the 2,6 positions of the morpholine ring. With its molecular formula C18H35NO and molecular weight of 281.5 g/mol, this substance exhibits unique physicochemical properties that make it valuable for specific industrial applications. The compound's structure combines the heterocyclic morpholine backbone with a twelve-membered cyclododecyl ring, creating distinctive steric and electronic characteristics. The substance carries significant safety considerations, classified under multiple hazard categories including reproductive toxicity (Repr. 2), specific target organ toxicity following repeated exposure (STOT RE 2), and severe skin corrosion (Skin Corr. 1C). It also presents strong skin sensitization potential (Skin Sens. 1A) and poses acute and chronic aquatic toxicity risks. The "Danger" signal word and multiple GHS pictograms (GHS08, GHS05, GHS07, GHS09) emphasize the need for stringent handling protocols and appropriate personal protective equipment. Industrial applications typically involve its use as a specialized chemical intermediate and catalyst component, particularly in polymer chemistry and materials science applications. The compound's unique morpholine structure makes it valuable in formulations requiring both basic nitrogen functionality and specific steric properties. This positions it alongside other specialty chemicals like (Z)-octadec-9-en-1-amine in applications requiring tailored molecular architectures. Transportation falls under ADR Class 8, reflecting its corrosive nature and requiring appropriate packaging and documentation. OYSI maintains technical-grade supplies of 4-cyclododecyl-2,6-dimethylmorpholine for qualified industrial customers across Europe.
