Overview
Dihydroxycoumarin is a derivative of coumarin, featuring two hydroxyl groups (-OH) attached to its benzene ring. It is widely studied for its bioactive properties, including antioxidant and UV-absorbing capabilities. The compound is commonly synthesized for use in pharmaceuticals, cosmetics, and research applications. Its structural similarity to natural coumarins makes it a versatile intermediate in organic synthesis. Industrially, it is valued for its stability and compatibility with various solvents, though its handling requires precautions due to potential irritant effects.
Physical and Chemical Properties
Dihydroxycoumarin appears as a pale yellow to white crystalline powder with a melting point range of 200-220°C. It is soluble in polar organic solvents like ethanol and methanol but has limited solubility in water. The compound exhibits strong UV absorption, making it useful in sunscreens and light-stabilizing formulations. Its molecular structure allows for chelation of metal ions, which is exploited in certain pharmaceutical and cosmetic applications. The presence of hydroxyl groups enhances its reactivity, enabling modifications for targeted chemical synthesis.
Main Applications
In the pharmaceutical industry, dihydroxycoumarin serves as an intermediate for anticoagulants and anti-inflammatory drugs. Its antioxidant properties are leveraged in skincare products to combat oxidative stress. Additionally, it is used in organic synthesis to create complex molecules for research and industrial purposes. The compound's UV-absorbing characteristics make it a candidate for sunscreen formulations and polymer stabilizers. In niche applications, it acts as a fluorescence probe in biochemical assays due to its photoluminescent properties.
Safety and Storage
Dihydroxycoumarin should be handled with care to avoid inhalation or skin contact, as it may cause irritation. Proper personal protective equipment (PPE), including gloves and goggles, is recommended. Storage conditions should prioritize cool, dry environments, ideally in airtight containers to prevent degradation. In case of exposure, rinse affected areas with water and seek medical advice if irritation persists. Disposal must comply with local regulations for organic compounds to minimize environmental impact.
B2B Procurement Guide
When sourcing dihydroxycoumarin, prioritize suppliers with certified quality control processes. Request certificates of analysis (CoA) to verify purity (typically ≥98% by HPLC) and batch consistency. Pricing varies based on quantity and purity, with bulk purchases often offering cost advantages. Consider logistical factors such as packaging (e.g., foil-lined bags for light-sensitive storage) and lead times. Establish long-term contracts with reliable suppliers to ensure steady supply and negotiate favorable terms for repeat orders.
