Overview
Emodin is a naturally occurring anthraquinone derivative found in plants like rhubarb and buckthorn. It is widely studied for its bioactive properties, including potential anti-inflammatory, anticancer, and antimicrobial effects. The compound has a distinctive orange-yellow color and is used in both traditional medicine and modern pharmaceuticals. In industrial contexts, emodin serves as a precursor for dyes and pigments due to its vibrant hue. Its dual role in therapeutics and manufacturing makes it a versatile chemical for B2B buyers, particularly in the pharmaceutical and chemical sectors.
Physical and Chemical Properties
Emodin crystallizes as an orange-yellow powder with a melting point of 256–257 °C. It is sparingly soluble in water but dissolves readily in organic solvents like ethanol and methanol. The compound’s anthraquinone structure contributes to its stability under standard storage conditions. Its molecular weight of 270.24 g/mol and CAS number 518-82-1 are key identifiers for procurement and regulatory compliance. Emodin’s solubility profile and crystalline form are critical for formulation in pharmaceutical and research applications.
Main Applications
Emodin’s primary use is in pharmaceuticals, where it is investigated for its potential to modulate cellular pathways, including those involved in cancer and inflammation. It is also a component of traditional Chinese medicine formulations. Beyond therapeutics, emodin is employed as a dye intermediate in textiles and coatings due to its vivid color. Research laboratories utilize it as a biochemical tool to study oxidative stress and enzyme inhibition.
Safety and Storage
Emodin should be handled with care, as it may cause skin or eye irritation. Proper PPE, including gloves and goggles, is recommended. Storage conditions should prioritize cool, dry environments away from direct light to prevent degradation. Regulatory guidelines, such as those from OSHA or REACH, may apply depending on the region. Always review Safety Data Sheets (SDS) provided by suppliers for specific handling instructions.
B2B Procurement Guide
When sourcing emodin, prioritize suppliers with certifications like ISO or GMP to ensure quality. Key procurement considerations include purity (typically 95–98% by HPLC), packaging (sealed, light-resistant containers), and compliance with end-use regulations. Prices vary based on purity and quantity, with bulk purchases often discounted. Request samples for lab validation before large-scale orders, and confirm lead times to align with project timelines.
