Description

Pallavicinin is a naturally occurring furanocoumarin compound isolated from plants of the Palea and Peucedanum genera, recognized for its photobiological activity and structural role in plant defense mechanisms. It matters to research-driven industries due to its well-documented interaction with DNA under UV-A irradiation, enabling targeted applications in photochemotherapy and molecular probe development. Pharmaceutical R&D laboratories, academic research institutions, and specialty fine chemical manufacturers rely on high-purity Pallavicinin CAS NO 156250-64-5 for mechanistic studies, reference standard preparation, and synthetic intermediate development.

Application

• Photodynamic therapy (PDT) research — as a model photosensitizer for UV-A–activated cytotoxicity studies
• Reference standard in HPLC and LC-MS quantitative analysis of furanocoumarins in botanical extracts
• Synthetic building block for derivatization into photoaffinity labeling agents
• Biological assay development — particularly in UVA-dependent DNA crosslinking and topoisomerase inhibition models
• Natural product pharmacognosy — authentication and quality control of Peucedanum praeruptorum and related Apiaceae species
• Photochemical kinetics studies — investigating singlet oxygen quantum yield and triplet-state lifetime

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches are verified for identity (IR, HPLC retention time match), purity (≥98.0% by HPLC), and absence of critical impurities (heavy metals <5 ppm, residual solvents per ICH Q3C). Testing aligns with ACS Reagent Grade specifications and supports GMP-aligned research environments.

Storage

Preserve in a tightly closed container, protected from light. Store at 2–8 °C under inert atmosphere (nitrogen or argon) to prevent oxidation and photodegradation. Keep desiccated; avoid exposure to ambient humidity.
