Putrescine and cadaverine are short aliphatic diamine compounds produced during the breakdown of amino acids in both living and dead organisms. What tests, including solubility, would you run in order to confirm their structure

In order to confirm the structure of Aliphatic Diamine Compounds, you'd need to run a set of tests. They are:

A. Preliminary or Initial Tests:

I. Tests for Physical Traits: this helps to determine or establish the physical traits of the substance. Characteristics such as State of Matter (e.g. solid, liquid) color, and odor.

II. Ignition test. This involves the application of heat on a minuscule amount of the compound or substance using a metal spatula. This helps to prove whether the compound is aliphatic or aromatic. An aliphatic compound such as methylated spirit is aliphatic because it produces a luminous flame. Vegetable Oil on the other hand is aromatic because it produces a sooty flame.

B. Physical Constants

This test aims to establish the boiling and melting points of such a substance.  

C. Analysis for elements present

D. Solubility tests

Explanation

Amine compounds are easily distinguishable by their odors. Amine odors have a somewhat fishy almost putrid quality.

When they are at room temperature,  they are present as gases and can easily evaporate in their liquid state.

Their relative densities are lower than that of water. with the exception of aromatic amines.
