2.5-Dioxo-3-Methylthiophene stands out in the world of chemical raw materials. This compound belongs to the thiophene family, with a molecular formula of C5H4O2S. Its structure presents a five-membered ring, combining sulfur and oxygen atoms with a methyl group tucked at the third position. This mix shapes the compound’s reactivity and suitability for multiple chemical processes. As a material, it draws attention for its specific chemical behavior and the unique physical characteristics its ring structure offers, including reactivity with nucleophiles and resilience under certain reaction conditions.
2.5-Dioxo-3-Methylthiophene typically appears as off-white or pale yellow flakes, powders, or sometimes small solid pearls. It rarely comes in liquid form under standard laboratory conditions. The substance forms crystalline solids, which show stability at room temperature but break down when exposed to intense heat or direct ignition sources. Looking at density, it lands near 1.40 g/cm3. The crystals do not dissolve well in water, but organic solvents such as acetone, chloroform, and DMSO handle them much more efficiently. Comparing to other heterocyclic compounds, this one holds its own for toughness and sustained reactivity in organic synthesis.
Each batch of 2.5-Dioxo-3-Methylthiophene generally meets strict industry specifications—purity often exceeds 98%. The melting point runs between 100 and 102°C, hinting at ease of purification through recrystallization. Detailed structure analysis points to the significance of both carbonyl groups and the ring-bound sulfur for specific reactions, such as cycloadditions or substitutions. This combination shapes both chemical utility and how the substance must be handled on the production line. The HS Code for this compound can be found under 29349990, cataloging it among other heterocyclic base products for regulatory and customs purposes.
Many chemists turn to 2.5-Dioxo-3-Methylthiophene as a starting point for synthesizing pharmaceuticals, agrochemicals, and advanced organic intermediates. The methyl and carbonyl groups open doors for crafting a variety of molecules, whether it’s a new drug precursor or a unique polymerizing agent. This makes it valuable in R&D labs, custom synthesis outfits, and pilot plants, offering workable raw material for further research or production runs. Some plastics and resins also start out with similar building blocks, showing the versatility of this thiophene derivative across many fields.
While working with 2.5-Dioxo-3-Methylthiophene, safety remains a priority. The flakes and powdered forms should not be inhaled, ingesting them leads to harmful effects, and direct skin contact carries risk of irritation. Inhalation of dust may provoke respiratory complaints. Use of gloves, protective eyewear, and efficient ventilation keeps risks down. Its safety data sheet classifies it as harmful if swallowed, and it poses risk for aquatic environments if released in large quantities. Proper labeling, storage in cool, dry environments, and strict separation from food and animal feeds form basic handling standards. Disposal should follow hazardous waste protocols, not generic landfill or drains.
The physical form of 2.5-Dioxo-3-Methylthiophene shifts across production batches. Flakes and powders pack efficiently in drums, with density hovering just above standard organic solids. Larger pearls or crystals take up more space per mass, impacting storage and shipment calculations. Most applications in solution lean on DMSO or acetonitrile, which hold the compound at room temperature and avoid hydrolysis. These solutions do not last indefinitely; heavy light or oxygen exposure eventually degrades the active compound. Suppliers often specify bulk density, crystal form, and storage advice on datasheets sent with each order, giving users up-to-date material stats for their process controls.
Anyone involved in specialty chemicals or advanced material sciences will run into 2.5-Dioxo-3-Methylthiophene on occasion. Not many alternatives offer quite the same reactive backbone with robust methyl and oxo functionalities tied to sulfur. Where process engineers look for comparable performance, other thiophene derivatives may step in, yet those swaps often mean changes in product purity or downstream reaction scope. Improving safety protocols, automating material transfer, and using digital material tracking can cut workplace hazards and help chemists, operators, and managers keep supply chain reliability high. Regulatory updates and environmental standards will continue shaping how this chemical is sourced, shipped, and processed in the future.
