2-(1,3-Dioxo-1,3-Dihydro-2H-Isoindol-2-Yl)Ethane-1-Sulfonic Acid-Potassium, known in laboratories as a well-characterized synthetic molecule, stands out with its complex cyclic imide core and a sulfonic acid side chain neutralized by potassium. The structure, bridging a phthalimide ring system with an ethanesulfonic acid group, creates unique solubility and reactivity profiles when compared to other sulfonic acids. Under typical conditions, it appears either as a pale, dense powder or a fine crystalline solid. The substance has found a dedicated following in the chemical synthesis field, particularly in specialty manufacturing environments and advanced pharmaceutical labs, because that structural combination brings beneficial properties difficult to find elsewhere. It is not just another raw material; it often plays a direct, foundational role in whatever process you bring it to.
The formula for this compound is C10H8KNO5S, highlighting a potassium cation that balances the negatively charged sulfonate moiety. In my time working with analytical reagents, I've learned the importance of a material's density and crystal formation. For this compound, a measured density typically rests around 1.8–2.1 grams per cubic centimeter, depending on the synthesis route and drying process. This density translates to easy handling, especially when weighing solids for batch reactors or lab-scale trials. The material usually comes in the form of solid flakes or a fine powder rather than liquid or pearl forms, offering consistent flow and mixing in solid-phase applications. Crystals may demonstrate a slight translucency, hinting at purity levels and the absence of moisture or chemical decomposition. Robust in air-stable conditions, the compound dissolves well in polar solvents, particularly water; that property widens application potential in both aqueous and mixed-solvent systems. I recall preparing buffer solutions in the lab where crystalline flakes dissolved with surprising efficiency, leaving little residue and minimal tweaking of pH necessary. This immediate solubility saves time, reduces operational headaches, and benefits process reliability on the production scale.
Looking deeper into the technical side, exact specifications vary depending on the supplier. Most reputable sources maintain chemical purity at or above 98%, with minimal moisture and less than 0.5% inorganic impurities—critical values for pharmaceutical synthesis or electronics manufacturing. The molecular weight sits at roughly 309.34 g/mol. Because this compound features a potassium salt, it typically resists hygroscopic behavior, so long-term storage issues arise less frequently than with sodium analogs or free acids. If mishandling or contamination occurs, you see degradation as clumping, yellowing, or uneven dissolution, signals I’ve learned to watch for during inventory checks or prep work.
In the market, products containing 2-(1,3-Dioxo-1,3-Dihydro-2H-Isoindol-2-Yl)Ethane-1-Sulfonic Acid-Potassium target specialty synthesis, often supporting coupling reactions or used as intermediates for dyes, pharmaceuticals, and certain agrochemicals. Plant operators know the difference that a well-defined, consistently produced starting material brings. From my experience developing analytical standards, slight shifts in crystal size or purity lead to costly downstream process disruptions. Reliable raw materials boost output quality and reduce waste. It also matters from a commercial perspective; chemicals meeting tight HS Code standards avoid customs hold-ups and regulatory headaches. For this compound, HS Code categories typically fall under 2933 for heterocyclic compounds, swinging customs applications toward the pharmaceutical rather than commodity chemical sector. Documentation around batch numbers, synthesis methods, and purity levels reflects not just transparent sourcing but product safety and traceability expectations that have grown stricter every year.
Handling any specialty chemical requires clear respect for safety and health risks, even for those categorized as only mildly hazardous. Phthalimide derivatives like this one do not create toxic vapors during ordinary handling, but dust or contact with mucous membranes can irritate skin, eyes, or the respiratory tract. During years working with similar acids and salts, gloves and basic protective eyewear became non-negotiable. Proper storage in cool, dry spaces forms the backbone of long-term stability, keeping the material free from excess humidity and reactive atmospheres. As a potassium salt, it tends to resist oxidation more than free acids but should never be stored alongside strong oxidizers or acids. Waste disposal aligns with standard organic salts—controlled incineration, compliance with local environmental codes, and contained transport to hazardous waste facilities. Mishaps remain rare, but even minor spills should get immediate cleanup to avoid slips, accidental mixing, or contact with incompatible chemicals. Material safety data sheets echo what everyday work shows: preparedness and proper labeling keep teams safe even in the busiest labs and plants.
One thing that stands out across specialties is the recurring battle with supply chain uncertainties and regulatory shifts. Chemicals like this, with defined end-user requirements and strictly enforced purity, often run into procurement delays, sourcing inconsistencies, or the need for adaptive storage as batch sizes and safety needs fluctuate. In my own work with purchasing and inventory teams, tracking every shipment—down to individual lots—became essential as import rules tightened and customer audits intensified. Solutions never hinge on a single tactic. Raising supplier standards, pushing manufacturers for full batch traceability, and keeping safety stock on site all offer partial buffers against disruption. Regulatory awareness, especially with evolving global HS Codes and chemical restrictions, also informs buying decisions and storage protocols. The margin for error narrows further every year, making transparency and openness about sourcing, purity, and handling more vital than ever for companies large and small.
