Description

4'-Demethyleucomin CAS NO 34818-83-2 is a specialized organic compound belonging to the class of coumarin derivatives, valued for its role as a key synthetic intermediate and reference standard in advanced chemical research. Its precise molecular structure makes it an essential building block for developing novel pharmaceutical compounds and fine chemicals. This high-purity material is primarily targeted at research institutions, pharmaceutical development laboratories, and manufacturers of active pharmaceutical ingredients (APIs) requiring reliable and well-characterized intermediates.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of more complex coumarin-based drug candidates and active pharmaceutical ingredients (APIs).
• Chemical Reference Standard: Used as a high-purity analytical standard for method development, validation, and quality control in pharmaceutical and chemical analysis.
• Academic & Industrial Research: A valuable tool for studying structure-activity relationships (SAR), reaction mechanisms, and developing new synthetic methodologies in organic chemistry.
• Fine Chemical Synthesis: Employed in the production of specialty chemicals, dyes, and fluorescent markers where the coumarin scaffold is required.
