This chromene-based carboxylic acid integrates a reactive acetic acid handle with a fluorescent 7-amino-2-oxo-2H-chromen-4-yl moiety, enabling direct conjugation in bioconjugation workflows. The electron-rich chromone scaffold enhances solubility and stability under standard conditions.
2-(7-Amino-2-oxo-2H-chromen-4-yl)acetic acid serves as a versatile building block for the synthesis of coumarin-based scaffolds with enhanced solubility and functional group handle availability. The carboxylic acid moiety enables direct amidation or esterification, while the 7-amino group supports derivatization via acylation or diazotization. Its stability under standard bench conditions facilitates purification and integration into multi-step sequences, making it suitable for medicinal chemistry campaigns targeting kinase inhibitors and fluorescent probes.
