Amidek

Amidek is a hypothetical organic molecule used in chemistry education and theoretical discussions to illustrate amide chemistry. Defined by a standard amide bond linking a carbonyl-bearing fragment to an amine-bearing fragment, amidek serves as a simple model for studying resonance, hydrolysis, and conformational behavior without the complexity of real-world molecules.

Properties commonly ascribed to amidek in teaching materials include neutrality near physiological pH, moderate polarity, and the ability to participate in hydrogen bonding. Its simple structure makes it convenient for discussing infrared carbonyl stretching around 1650 cm-1, NMR signatures of amide protons, and the partial double-bond character of the C–N bond that restricts rotation.

Synthesis, in pedagogical contexts, is described conceptually as coupling a carboxylic acid fragment with an amine fragment under standard amide-coupling conditions, such as carbodiimide- or carbonyl-activating reagents, followed by purification. Reactions like acid or base hydrolysis are used to illustrate amide stability and the influence of substituents on rate.

Uses of amidek include illustrating core concepts in organic synthesis, spectroscopy, and structure–activity relationships in a simplified framework. In literature and classroom materials, amidek is treated as a stand‑in compound rather than a real, cataloged chemical, and multiple variants may be shown to highlight different teaching points.

Name origin and status: the name combines the term "amide" with a placeholder suffix, reflecting its role as a didactic example rather than a confirmed real-world substance.
