1H,5H-Pyrazolo(1,2-A)Pyrazol-1-One, 2,3-Diamino-6,7-Dihydro-, Dimethanesulfonate represents a unique compound standing out in chemical research and manufacturing. People seek this substance for its rare structure, allowing for applications not easily tackled by common agents. Built on a sturdy pyrazolo-pyrazolone core, this chemical brings specificity through its diamino functionality at the 2 and 3 positions on the ring—a feature that’s proven valuable during process development and molecule building. Dimethanesulfonate acts as the counterion, increasing solubility, which can widen practical use across solvent systems and solid forms.
Material handling experts recognize this substance as remarkably versatile—it takes on several forms, from fine powders and granular pearls to solid flakes and clear crystalline masses. The choice often boils down to downstream requirements. Powdered samples generally speed up dissolution and blending, while pearls and flakes offer measured dosing and steady flow for process operators. Crystalline forms shine in analytical labs for structure confirmation, while concentrated liquid or prepared solutions help teams needing precise molarity in reaction vessels. Plant managers often prefer bulk solids, measured in kilograms or liters, while labs might pick smaller volumes or weight-based units to minimize exposure and maximize control.
The compound’s backbone fuses a pyrazole ring to a pyrazolone structure in a rigid framework, adorned with two primary amine groups and further stabilized by a sulfonate. With a molecular formula encapsulating these groups—carbon, hydrogen, nitrogen, oxygen, sulfur—the structure stacks up with a clear arrangement, tested by NMR, IR, and sometimes crystallography. Researchers can draw a direct relationship between layout and reactivity, especially when investigating new target compounds or derivatives for pharmaceutical and technical uses.
Looking at properties, this compound stands out due to its moderate density, measured by careful weighing and volume calculation. It maintains a solid state at room temperature, transitioning from crystals to powder with agitation or grinding. The material avoids caking in controlled humidity, a quality prized for operators stacking containers in storage rooms. Melting point sits higher than room temperature, giving confidence against accidental softening or clumping. True to its architecture, it dissolves readily in polar solvents like water and some alcohols, helped along by the sulfonate anion. The presence of amino groups pushes reactivity higher, which chemists notice when linking or modifying molecules. Vapor pressure reads low, so airborne release stays minimal in standard handling environments, reducing inhalation risk.
Lab and factory teams treat this specialty material with respect. While not the most aggressive substance, the diamino motif triggers concerns for skin and eye irritation. Protective clothing—gloves, goggles, coveralls—keeps accidental splashes away from workers. If handled in poorly ventilated rooms, powders might lead to exposure through dust, though large crystals and pearls drop this hazard. Literature sometimes marks the sulfonate group as less risky than other counterions but always prompts staff to keep material contained and away from open drains, avoiding environmental release. Reaction with acids or strong oxidizers can produce unexpected fumes, calling for special attention during process scale-up or when running lengthy synthesis sequences. Facilities install spill kits and emergency showers so teams never face a worst-case exposure without rescue equipment.
Each batch comes with a certificate showing purity—numbers above 98% and up remain the standard for technical applications, while labs developing pharmaceuticals push for even cleaner samples. Batch records list secondary markers like water content, often checked by Karl Fischer, and trace metals scanned by ICP-MS for critical uses. Density checks during packing verify nobody sells lightweight or adulterated product. Suppliers offer flakes, crystals, and powder in bags, drums, or jars, and regularly detail filling weights alongside gross-to-net calculations to simplify user audits. Listings often include details about average particle size, bulk density, and moisture limits, which keep customers satisfied when product flows evenly into reactors or process hoppers.
Raw materials and intermediates like this one must cross borders under clear classification. The Harmonized System (HS) Code ranks high on every shipping label, reading as an identifier for customs officials, regulatory bodies, and end users. Chemical customs codes typically reflect the compound’s functional groups and overall class, streamlining tax assessments and compliance with regulatory requirements. Companies shipping bulk drums or smaller laboratory bottles use correct labels to avoid border delays and surprise inspections. Environmental rules—especially for hazardous waste—demand exact tracking, so having a standard HS code makes import, export, and domestic transport less of a gamble.
Companies that rely on this compound treat sourcing as a mission-critical activity. Manufacturers look for stable suppliers to keep operations running through volatile markets or shifting global demand. Standard procurement practice involves vetting material at the point of origin, securing consistent quality, and verifying purity with incoming batches. Reliable transit arrangements—often air-freight for emergencies—help meet project deadlines even when global supply chains falter. When shortages hit, labs sometimes look for synthetic routes or alternative raw materials, but few replacements match this compound’s unique blend of stability, reactivity, and handling safety. Inventory managers keep a close watch on re-order levels, knowing downtime costs more than premium spot purchases.
