2-Chlorobenzothiazole belongs to the benzothiazole family, standing out as a versatile and widely used organic compound. Significantly, it forms the backbone for a range of synthesis processes in chemical manufacturing. The chemical structure consists of a benzene ring fused with a thiazole ring, and a chlorine atom occupies the second position on the ring system. Chemists, scientists, and industry workers know this material for its distinctive molecular properties, which influence its performance in research and production environments.
You encounter 2-Chlorobenzothiazole as pale yellow crystalline solid, sometimes appearing as flakes or powder. Some batches might yield pearly granules or fine crystals, depending on the production process and purification level. On occasion, it arrives dissolved in suitable solvents, forming a useful liquid solution for those seeking easier dosing or mixing. You rarely see it in bulk liquid form due to low solubility in water and a relatively high melting point that keeps it stable as solid under room temperature.
Describing the core structure, the molecule features a benzene ring bonded directly to a thiazole, which picks up a single chlorine atom at the ortho position. The molecular formula reads C7H4ClNS, with a molecular weight of about 169.63 g/mol. Such compact size lets it act as a building block or intermediate in larger synthetic routines. The HS Code, which helps track global commerce and trade, often lists this compound under 2934990000, covering other heterocyclic compounds with nitrogen hetero-atom only.
The observed melting point hovers between 42 and 44 °C, offering a guideline for storage and stability during warm seasons or unique conditions of bulk handling. The density clocks in around 1.38 g/cm3, meaning you pack a fair amount of substance in a relatively modest volume. Most 2-Chlorobenzothiazole samples present as slightly yellow, hinting at purity or trace contaminants, both of which play a crucial role in sensitive applications. The vapor pressure remains low at room conditions – this limits its evaporation but calls for good ventilation during processes involving heat or fine powder. Water solubility drops off rapidly due to the aromatic core, but you’ll see high compatibility with common organic solvents like ethanol, ether, or even chloroform.
Handling 2-Chlorobenzothiazole requires strict attention to safety due to its irritant and harmful nature. Prolonged skin or eye contact often leads to irritation or allergic reactions, and inhaling dust or vapors must be avoided. Chemical safety data notes it as hazardous for both operators and the immediate work environment; accidental spills or poor hygiene raise the chances of health risks. Its classification in many regulatory systems highlights potential harm for aquatic life and the need for careful waste management. Workers need gloves, protective glasses, and well-ventilated enclosures to reduce exposure. Chemical storage demands airtight containers, clear labeling, and systematic inventory checks. I’ve noticed over time that proper risk communication and training cut incidents dramatically, emphasizing that protocols mean more than paperwork—they keep teams healthy and operations smooth.
You find 2-Chlorobenzothiazole as a raw material in the production of agricultural chemicals, pharmaceuticals, and specialized dyes. Many of these sectors use its reactivity at the chlorinated site to introduce functional groups that produce desired effects—herbicidal, fungicidal, or antibacterial. On industrial scales, it works as an intermediate, letting teams manufacture complex molecules efficiently. In the research setting, organic synthesis relies on this compound for the preparation of ligands, catalyst frameworks, or as reaction probes. Each batch comes with a certificate confirming crucial details like purity, residual solvents, and melting point, and these specifications make all the difference when end users seek reliable performance or reproducibility.
Lowering workplace and environmental risk starts with good planning and deeply ingrained habits. Regular safety reviews ensure containment systems work as designed, without clogging or leaks. Chemical hygiene involves not only checking stock expiration dates but also updating handling instructions as new data emerges. In my experience, teams working daily with hazardous chemicals benefit from open reporting cultures and easy access to material safety data sheets. Waste streams containing 2-Chlorobenzothiazole demand careful separation to prevent toxic releases—partnering with certified waste processors brings peace of mind and aligns with regulations. Beyond worker safety, tracking emissions and runoff protects local ecosystems and keeps community trust strong.
Sharing clear descriptions and practical knowledge about chemicals like 2-Chlorobenzothiazole matters for several reasons. Chemical producers, warehouse operators, buyers, and end users all need to know exactly what comes in each shipment: form, strength, density, and storage needs. Accurate HS Codes help trade partners pass customs checks and ensure compliance with national laws. Users can’t cut corners on safety or environmental responsibility, especially with hazardous materials. Focusing on complete documentation and open communication keeps production lines moving, shields workers from real danger, and sets an example for responsible industry practice.
