Medchemexpress LLC 7-methoxycoumarin-3-carboxylic acid | 20300-59-8 | MFCD00452770 | 97.0% | 220.18 g·mol⁻¹ | C11H8O5 | 5 G
7-methoxycoumarin-3-carboxylic acid is a coumarin-derived fluorescent dye (CAS 20300-59-8) commonly used to label peptides and amines and for HPLC derivatization. It is a white to off-white solid (C11H8O5, MW 220.18 g·mol⁻¹) that exhibits blue fluorescence; optical properties are solvent- and pH-dependent and should be validated for the intended assay.
- Fluorescent label suitable for peptide and amine conjugation.
- Useful for HPLC derivatization and fluorescent detection.
- Blue fluorescence with excitation and emission peaks that vary by solvent and pH.
- Available as a solid, white to off-white powder for easy handling.
- Well-characterized chemical identity and molecular weight for reproducible results.
