3 Nitro Benzene Sulfonic Acid Granules 80% come to the industry as a strong sulfonating agent used for a range of chemical syntheses and industrial applications. This compound belongs to the family of aromatic sulfonic acids. Seeing it in use across dye manufacturing, pharmaceutical synthesis, and electroplating, its relevance draws on both its chemical structure and robust physical properties.
This molecule carries the formula C6H5NO5S and forms part of the nitrobenzenesulfonic acid group. The molecular layout places a nitro group (NO2) at the third position of benzene’s ring system, with a sulfonic acid function (SO3H) nearby. Together these groups drive the reactivity of the material in both acidic and oxidation environments. Each molecule weighs in with a molecular mass of approximately 219.18 g/mol. The sulfonic acid framework links to robust solubility in water and polar solvents, acid strength, and increased reactivity with organic and inorganic compounds.
Granules at the 80% activity level look yellow-brown and show up in solid, flake, and powdered textures. Some processes shape them into pearl or crystalline forms, which makes handling easier on a large scale. Their physical density hits around 1.7 g/cm³, making the material dense and substantial in each shipment. In my experience working around chemical supply, you quickly notice the granular version keeps dust low compared to powder, so it helps with cleaner dosing and transport. Each solid batch offers consistent particle size, which factors into process efficiency and safety, especially when moving thousands of liters in a chemical plant.
Product strength matters. With 80% purity, users rely on a consistent profile, blending strength and reactivity with manageable handling qualities. Maximum moisture content stays low to prevent caking and unwanted reactions. Key specs include active ingredient percentage, bulk density, and melting point (close to 120°C). Flakes or solid granules resist humidity better than some powdered acids, extending storage life and making bagged shipments more reliable over long transport. The material generally ships as a strong acid granule, but some supply chains offer solutions in water, measured in grams per liter, for faster dosing into reactors or baths.
Customs and logistics use the HS Code 29049090 for nitro and nitroso derivatives like 3 Nitro Benzene Sulfonic Acid. Incoming shipments pass safety and documentation scrutiny because this group of compounds can fall under both chemical and hazardous goods lists. Regulatory status depends on end use, importing country, and workplace safety codes. Each time I’ve worked with these granules, shipping teams need up-to-date documents detailing hazard and composition, without which customs delays quickly pile up.
3 Nitro Benzene Sulfonic Acid Granules 80% count as hazardous for both operators and the environment. The acid’s strong corrosiveness and oxidizing potential require protective equipment, from basic gloves and goggles to full chemical suits during bulk handling. Fumes can irritate respiratory systems, so good ventilation becomes a must. Accidentally mixing with incompatible chemicals, especially bases or combustible materials, risks violent reactions. Emergency response plans make a difference here—when spills happen, prompt neutralization prevents both personal injury and damage to the facility. From my side, maintaining clear labeling and separation in storage cuts down on accidental exposure and complicated cleanup jobs.
The raw materials driving production include benzene, fuming sulfuric acid, and concentrated nitric acid. Sourcing quality feedstock cuts down on unwanted by-products and off-spec batches later in the process. Once synthesized, the product flows into dye intermediates, optical brighteners, and specialty surfactants. Some users in electronics rely on specific densities or granular forms to fine-tune metal surface cleaning and etching. My own projects connecting with specialty chemicals made clear that reliable supply and tight quality specs allow end users to keep their own syntheses predictable and cost-effective.
Minimizing risk begins with training. Operators need hands-on sessions covering personal protective equipment, emergency steps, and chemical compatibility tables. Automated handling—using auger feeders, closed transfer lines, and dust collection—reduces direct contact. Bulk packaging improvements, like lined drums or moisture-proof polyethylene bags, hold down contamination and make stacking safer. Where spillage stays a risk, spill kits with neutralizing agents provide a first-line defense. On the site level, scheduling regular hazard audits keeps complacency in check and lets every team member spot problems faster.
Trust in a chemical product builds on transparency, quality, and safety. 3 Nitro Benzene Sulfonic Acid Granules 80% matter because they connect upstream feedstock to the tailored needs of downstream industries. Regulatory updates push for tighter control of hazardous substances, so suppliers look for greener manufacturing, more robust packaging, and clear documentation every step of the way. Technology keeps improving material tracking and safety system response times. In the end, everyone in the chain—makers, transporters, end users—shares a stake in both safe handling and consistent supply, especially for materials that carry risk into any workplace or product.
