General structure of (primary) diamines. The primary amino groups (NH2) are marked blue, R is a divalent organic radical (e.g. a para- phenylene group). A diamine is an amine with exactly two amino groups. Diamines are used as monomers to prepare polyamides, polyimides, and …

Ethylenediamine | C2H8N2 | CID 3301 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Ethylenediamine contains total 11 bond (s); 3 non-H bond (s), 1 rotatable bond (s), and 2 primary amine (s) (aliphatic). Learn more about chemical structure at Mol-Instincts.

2022年9月15日 · Identify the general structure for an amine. Identify the functional group for amines. Determine the structural feature that classifies amines as primary, secondary, or tertiary. Use nomenclature systems to name amines.

2024年9月30日 · One other characteristic of amines is their odor. Low-molecular-weight amines such as trimethylamine have a distinctive fishlike aroma, while diamines such as cadaverine (1,5-pentanediamine) and putrescine (1,4-butanediamine) have the appalling odors you might expect from their common names.

Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2. This colorless liquid with an ammonia -like odor is a basic amine. It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6] .

Low-molecular-weight amines such as trimethylamine have a distinctive fishlike aroma, while diamines such as cadaverine (1,5-pentanediamine) and putrescine (1,4-butanediamine) have the appalling odors you might expect from their common names. Both of these diamines arise from the decomposition of decaying tissue.

An organic compound with multiple amine groups is called a diamine, triamine, tetraamine and so forth, based on the number of amine groups (also called amino groups) attached to the molecule. The chemical formula for methylene diamine (also called diaminomethane), for example, would be as follows: H 2 N-CH 2 -NH 2.

A diamine is an organic compound that contains two amine groups (-NH2) in its molecular structure. These compounds are significant in various chemical reactions, particularly in the formation of polyamides and other polymers.
