General Description

1-Propanaminium, N-(carboxymethyl)-N,N-dimethyl-3-[(1-oxo-10-undecen-1-yl)amino]-, inner salt is a chemical compound with various applications. It is an inner salt, indicating that its positive and negative charges reside within the same molecule. This chemical possesses a carboxymethyl group, which gives it the ability to bind to different substances. Furthermore, it contains a long chain of carbon atoms (10 undecenyl groups) attached to an amino group. This structure suggests that the chemical could potentially function as a surfactant, emulsifier, or a surface-active agent. However, further research is needed to fully understand the properties and potential uses of this compound.
