3,5-Xylenol belongs to the class of organic compounds known as phenols, serving key roles across several chemical manufacturing and industrial sectors. As an isomer of dimethylphenol, this compound brings unique traits based on its placement of methyl groups on the benzene ring. Chemists recognize its distinct molecular profile, rooted in the formula C8H10O, which combines the volatility and aromaticity of hydrocarbons with the reactivity of a hydroxyl group. 3,5-Xylenol appears in several forms, adjusting to industry demand for flexibility in handling—ranging from powder and solid to pearls, flakes, or even liquids, depending on storage, shipment, and application needs.
A clear mark of 3,5-Xylenol centers on its melting point, lying near 63–65°C, and a boiling point of approximately 220°C. The material presents as off-white to yellowish crystals or powder, offering good solubility in organic solvents such as ethanol and ether, but limited dissolvability in water. Density comes in at around 1.045 g/cm³, measured at room temperature, indicating a moderate weight that makes it manageable during transfer or mixing into reactions. Professionals involved in chemical manufacturing or research favor its sharp odor, as it assists in trace detection and safe handling. The HS Code for 3,5-Xylenol generally falls under 29071190, which covers phenol and its derivatives, streamlining customs processing and trade logistics.
Examining 3,5-Xylenol at the molecular level exposes a benzene ring, with methyl (–CH3) groups attached to the 3 and 5 positions, and a hydroxyl (–OH) group anchoring at the first site. This arrangement shapes both its reactivity and interaction with other chemicals. The structural formula, represented as (CH3)2C6H3OH, indicates imbalance between hydrophobic and hydrophilic features, which factors into its performance as a raw material for intermediates. The unique orientation of substituents on the aromatic ring helps chemists design derivatives needed for the production of various dyes, pharmaceutical ingredients, and plasticizers. Specific gravity and density readings let manufacturers calibrate dosing and batch mixing, supporting consistent results when scaling up process lines.
Most suppliers package 3,5-Xylenol as crystalline flakes, a dense powder, or even as fine pearls, loaded into moisture-controlled containers to prevent clumping or unwanted reactions. The physical state enables weighing with precision, important for laboratory analysis and bulk production. Liquid forms stem from heating the substance, which allows solutions to be prepared for high-efficiency applications in resin manufacture or antimicrobial agents. Its solid and slightly oily texture means minimal dust is released during handling, a small detail that matters for cleanroom technicians and plant workers managing air quality standards. In some workflows, the crystalline nature makes direct dosing possible with minimal preparation, speeding up processes that rely on tight production timelines.
Handling 3,5-Xylenol raises some safety concerns. It's classified as hazardous, flagged as harmful if swallowed, inhaled, or through skin contact, based on GHS (Globally Harmonized System) label requirements. The chemical poses risks of irritation or severe damage to eyes and respiratory systems. Experience has shown that personal protective equipment—nitrile gloves, chemical goggles, and strong ventilation—keeps accidents to a minimum, especially in tight spaces where fumes may build. In storage, well-sealed, labeled drums reduce the chance of leaks or unintended mixing. Environmental health perspectives stress responsible waste management, since traces released into wastewater can disrupt aquatic life due to its toxicity. Adhering to stricter spill-control measures and site-specific protocols shields both workers and local ecosystems. Emergency plans, including eye wash stations and spill kits, prove essential—a lesson many chemical industry veterans have learned through hard-won experience.
3,5-Xylenol has anchored itself as a key raw material in several branches of industry. Manufacturers draw on its chemical backbone to build up antiseptics, polymer additives, and intermediates for agricultural chemicals. The reactive hydroxyl group offers a gateway for further functionalization, enhancing outcomes in fine chemical synthesis. My own work in pilot-scale formulation projects demonstrated that the purity and specific density of starting 3,5-Xylenol often determined downstream yield and product stability. For users designing solutions and finished formulations, attention to source quality, verified by batch analytical data, proves vital to consistent process control. Regular review of storage procedures safeguards both product quality and worker safety. As global supply chains shift, reliable pricing and robust logistics for 3,5-Xylenol remain crucial, helped by clarity in HS Codes and compliance documentation. These practical steps turn a specialized chemical into a reliable building block across multiple production domains.
