Physical and Chemical Properties

Understanding the physical characteristics of 4-Methyl-3-nitrophenol is vital for safe handling and effective integration into synthesis processes. The compound exhibits a density of 1.32 g/cm3 and a melting point range between 78 and 81 degrees Celsius. Its boiling point is recorded at approximately 276 degrees Celsius, indicating thermal stability under standard processing conditions. The flash point of 125.2 degrees Celsius necessitates careful storage and handling procedures to maintain safety standards within the laboratory or production environment.

Additionally, the refractive index is measured at 1.596, which is a key identifier for quality verification during incoming inspection. These properties collectively ensure that the material performs predictably during nitration and coupling reactions common in dye manufacturing. Our technical team provides detailed safety data sheets and handling guidelines to support your operational safety protocols.

Industrial Applications

The primary application of 4-Methyl-3-nitrophenol lies in the production of hair dye intermediates. It acts as a crucial coupling component or precursor in the synthesis of oxidative hair colorants. The high purity level of our product minimizes side reactions, ensuring vibrant and consistent color results in the final cosmetic formulation. Beyond hair care, this chemical may find utility in the synthesis of certain agrochemicals and pharmaceutical intermediates, although its primary market focus remains within the cosmetic dye sector.

Manufacturers benefit from the reproducible quality of our material, which reduces batch-to-batch variation in final products. This consistency is essential for maintaining brand reputation and consumer trust in cosmetic lines. We work closely with R&D departments to understand specific formulation requirements and can offer technical guidance on integration.

Quality Assurance and Packaging

Quality is the cornerstone of our manufacturing philosophy. Each production batch undergoes rigorous testing using high-performance liquid chromatography (HPLC) to verify purity levels above 99.0%. We also monitor ash content, loss on drying, and heavy metal traces such as iron to ensure compliance with safety regulations. A Certificate of Analysis (COA) is provided with every shipment, documenting all test results for your quality records.

Standard packaging consists of 25 kg drums, designed to protect the integrity of the crystalline powder during transit. However, we understand that different logistics requirements exist. Therefore, we offer flexible packaging solutions according to customer requirements. Storage recommendations include keeping the product in a cool, ventilated place away from direct sunlight and moisture to prevent degradation. Our global logistics network ensures timely delivery to facilities worldwide.
