[(2-Methoxyphenyl)Amino]Methanesulphonic Acid is a specialty chemical shaped by a unique blend of organic and sulphonic structural traits. It’s built on a phenolic backbone altered with a methoxy group, an amino bridge, and a robust methanesulphonic acid arm. Its molecular formula gives insight into this structure: C8H11NO4S, holding a precise blend of functional groups. The substance takes solid form at room temperature, sometimes found as flakes, crystalline powder, or even small pearls depending on how it’s processed or packed. Color often runs from near-white to pale beige, and the solid handles atmospheric conditions with a degree of resilience maintained by its molecular construction.
This compound stands out because of its distinct physico-chemical characteristics. At normal conditions, it shows a specific density ranging from about 1.35 to 1.45 g/cm3, giving it a sturdy presence compared to typical organic powders. Solubility lands squarely in the water-soluble camp, thanks to the sulfonic acid group, with quick dispersion when introduced into aqueous solutions. Crystals may form as needle- or plate-like shapes, which points to a level of purity and well-defined crystallization. Its melting point usually lies above common room temperatures, sometimes reaching beyond 130°C, giving it good thermal stability through a broad range of industrial applications.
This material isn’t just a chemical name—it’s a product grounded in decades of synthetic chemistry. Used as a raw material in both pharmaceutical research and advanced material manufacturing, it often enters the stage during the creation of dyes, drugs, or specialty additives. The molecular structure lends itself to modifications, and chemists often look for those methoxy and sulpha traits when building complex molecules. Storage and use call for careful management, as even a stable compound like this deserves respect for its acid and aromatic components. Safe handling means keeping it dry, storing it away from bases and oxidizers, and using sealed containers marked clearly in line with industry standards.
International trade follows the Harmonized System (HS) code for tracking and regulation purposes. [(2-Methoxyphenyl)Amino]Methanesulphonic Acid commonly fits under HS Code 292229, grouping it with other aromatic sulfonic acids and their derivatives. This code matters for anyone moving large quantities across borders, handling customs documentation, or ensuring taxes and duties stay transparent. In regulatory frameworks, correct identification keeps shipments running smooth, and prevents accidents or misuse as authorities can check and confirm safety guidelines.
Safety on the job always sits at the top of mind when handling chemicals like this acid. It’s not an everyday household item. While not as noxious as some heavy industrial acids, direct contact with skin, eyes, or prolonged inhalation still brings risk—irritation, sensitivity, in rare cases respiratory or dermal reactions. Spills or dust clouds mean crews don gloves, goggles, and often dust masks or respirators, especially in enclosed spaces. Emergency water stations should never go missing from a workspace, and disposal lines up closely with local hazardous waste rules. Anyone using the material as a raw feedstock, or processing it into pharmaceutical ingredients, knows that material safety data sheets (SDS) give honest, clear guidance.
Shipping departments appreciate its typical solid-state, which makes bulk handling practical compared to volatile liquids or fine mists. Densities hovering near 1.4 g/cm3 let operators calculate storage needs and logistics without undue burden. For lab-scale work, technicians dissolve the substance in distilled water, common organic solvents, or buffered solutions depending on the end use. Chemists eyeing its function in synthesis often focus on its ability to donate sulfonic acidity or act as a nucleophile, exploiting its amino linkage and methoxy group during complex transformations.
Knowledge of product form—whether flakes, powder, pearls, or crystals—translates to real, daily impacts for those mixing, blending, or weighing batches. Knowing if it clumps, cakes, or flows freely changes the pace in a production environment. Understanding the safe, hazardous, or harmful sides isn’t theoretical to a plant operator managing waste streams, or an R&D tech scaling up a new process. Specifications like purity, particle size, and bulk density change the game for anyone developing a consistent product in highly regulated fields. Regulatory professionals, freight specialists, and quality managers all learn that cutting corners on material description can turn a routine job into an expensive lesson.
Better labeling, reliable safety training, and detailed documentation—these all move industries forward. Accurate molecular and physical property sheets—accessible to everyone in a supply chain—cut down on errors and speed up troubleshooting. Industrial sites benefit from automation in dosing and mixing, especially when working with powders known for dusting or clumping. Publications and supplier databases that provide not just CAS numbers but also HS codes, melting points, particle trial data, and handling tips protect jobs and equipment. Chemical manufacturers who invest in clear handling advice, robust container design, and continued customer support reach a level of trust that helps customers navigate the maze of daily operations.
From direct work in both academic and industrial labs, it becomes clear that small details in chemical form (flake, powder, pearl, crystal) influence results, safety, and efficiency. Over time, those using [(2-Methoxyphenyl)Amino]Methanesulphonic Acid know the value of routine checks—verifying product lots, updating safety data, and sharing firsthand lessons from spills or unexpected reactions. Whether in pharmaceutical research labs or large-scale material plants, the path to improved safety and productivity is paved with hard-won experience and a willingness to learn from both data sheets and daily work. The result—better products, safer workplaces, less waste, and a strong link between accurate technical info and real-world outcomes.
