7-Chloro-3-Methyl-1-Benzothiophene stands out as a halogenated benzothiophene used across research and industrial fields. With a recognizable aromatic structure that binds a chlorine atom at the seventh position, and a methyl group at the third, this compound contributes as a raw material in pharmaceutical synthesis and agrochemical design. Its chemical formula, C9H7ClS, captures the elements at play: nine carbon atoms, seven hydrogen atoms, a chlorine atom, and a sulfur atom. The molecular weight lands around 198.68 g/mol, shaping how this substance interacts and is handled during processes.
In handling 7-Chloro-3-Methyl-1-Benzothiophene, you’ll most often notice its solid state under room conditions. This substance can show up as off-white to light-yellow flakes, fine powder, or irregular crystals, hinting at minor variances that don’t change its function. It brings a characteristic, sometimes pungent odor, attributed to the arm of the benzothiophene skeleton. Solubility can lean toward organic solvents, such as dichloromethane or toluene, while water won’t break it down easily, pointing to its non-polar nature. The density usually sits close to 1.3 g/cm³. Melting points may rest in the realm of 60–90°C, shifting slightly due to different batches or minor impurities, but always respecting the thermodynamic profile that marks this raw material’s identity.
The backbone of 7-Chloro-3-Methyl-1-Benzothiophene tells much about its stability and roles. A benzene ring fused with thiophene, spiced up by a methyl and a chlorine, crafts a scaffold that resists easy oxidation and keeps macro-structure firm under normal handling. In labs and plants, this chemical stands up to most acids and bases when cold, but like a lot of aromatic thioethers, it can trade atoms or groups in specialized reactions. The presence of chlorine affects electronic properties, bringing moderate reactivity toward metal-catalyzed cross-coupling or nucleophilic substitution, which makes it a prime target in organic construction for producing specialized molecules.
You’ll spot 7-Chloro-3-Methyl-1-Benzothiophene in solid forms—flakes, powder, pearls, or crystals. Per batch, producers may adjust packaging, but keeping it air-tight and dry makes a difference. Volatility isn’t its main trait, so liquid or solution-based logistics don’t usually come into play except for synthesis steps. The chemical serves as a key building block for pharmaceutical intermediates, usually feeding advanced drug research and bug-resisting pesticide creation. These applications drive home the importance of material purity and reliable physical form, since the outcome of a lengthy process often traces back to the starting raw materials. The consistency of structure and practical density helps equipment dose, meter, and handle this compound in scaled-up settings.
7-Chloro-3-Methyl-1-Benzothiophene generally travels under the international harmonized system (HS) code for heterocyclic compounds: 2934.99. This coding matters for importers as tariffs, customs inspections, and storage rules all tie back to the correct ID. Many countries keep their eye on this class of chemicals, not only for legitimate industry but because some structures echo those in restricted or monitored compounds. Safety data and registration support market entry; product datasheets must detail its makeup, storage advice, and transport cautions for regulators and logistics partners alike.
No one wants surprises when working with new chemicals. 7-Chloro-3-Methyl-1-Benzothiophene, while not explosive or overtly flammable, warrants careful respect. Like many aromatic organics, dust or fumes could irritate the nose or skin, and ingestion or extended exposure could upset health. Some research points to harmful effects if inhaled in high amounts or handled without basic personal protective equipment. Never skip gloves or goggles; keep good airflow in work areas. Spill control revolves around containing solids—no rushing to mop up with water, since low solubility pushes for vacuum or sweep solutions. Waste should funnel into well-marked hazardous containers, not the regular bin, to keep downstream handlers in the loop and environmental impacts under check.
As someone working in labs and talking with plant operators, the hunt for greener chemistry never ends. Choices about solvents, containment, and waste steer how safely 7-Chloro-3-Methyl-1-Benzothiophene lands in new uses. Options like tighter reaction controls, single-use PPE reduction, and process recycling offer routes toward a safer, less harmful footprint. Sharing accurate information—full material specifications, measurable density, crystal or powder habits, hazards, and batch traceability—reinforces both trust and performance from source to application. Building a solid pipeline for training supports accident-free practice and boosts confidence among new chemists or operators dealing with sensitive intermediates like these.
The story of 7-Chloro-3-Methyl-1-Benzothiophene winds through every discipline that values careful design and practical safety. Drug innovation and crop protection work at the edge of what chemistry can deliver. In this space, clear and reliable data about raw materials, their properties, structure, density, and hazards, makes all the difference. Meeting supply chain demand, delivering in dependable form—whether solid flakes, powder, or pearls—puts the power of this compound into chemists’ hands, setting up success down the line. Making sure regulatory, physical, and human factors stay balanced means the people behind the beakers keep progress safe and smart.
