What is Ethyl Indole-2-Carboxylate?

Ethyl Indole-2-Carboxylate is an organic compound derived from the indole family, where an ethyl ester group is attached to the carboxyl group at the 2-position of the indole ring. It is a versatile chemical intermediate used in various organic synthesis applications, particularly in the pharmaceutical and chemical industries.

Chemical Structure and Properties

• Chemical Formula: C11H11NO2

• Molecular Weight: Approximately 189.21 g/mol

• Structure: It consists of an indole ring (a bicyclic structure combining a benzene ring fused to a pyrrole ring) with a carboxylate group at the 2-position, esterified with an ethyl group.

• Appearance: Typically appears as a colorless to pale yellow liquid or solid, depending on the purity and storage conditions.

• Solubility: Soluble in organic solvents like ethanol, methanol, and acetone; sparingly soluble in water.

• Stability: Stable under standard conditions, but it should be stored in a cool, dry place away from light and moisture to prevent degradation.
