1-(4-amino-1,2,5-oxadiazol-3-yl)-5-(4-ethoxyphenyl)-4-triazolecarboxylic acid ethyl ester

You're describing a compound with a very specific chemical structure. Let's break it down:

**1-(4-amino-1,2,5-oxadiazol-3-yl)-5-(4-ethoxyphenyl)-4-triazolecarboxylic acid ethyl ester**

* **1,2,5-oxadiazole:** A five-membered ring containing one oxygen atom and two nitrogen atoms.
* **4-amino:** An amino group (-NH2) is attached to the 4th position of the oxadiazole ring.
* **3-yl:** Indicates that the oxadiazole ring is attached to the rest of the molecule at the 3rd position.
* **4-triazolecarboxylic acid:** A triazole ring (a five-membered ring with three nitrogen atoms) containing a carboxylic acid group (-COOH) at the 4th position.
* **5-(4-ethoxyphenyl):** A phenyl ring (C6H5) with an ethoxy group (-OCH2CH3) at the 4th position, attached to the 5th position of the triazole ring.
* **ethyl ester:** The carboxylic acid group is esterified with an ethyl group (-CH2CH3).

**Importance in Research:**

This compound is likely being studied for its potential **biological activity**. Here's why:
