Bisguanidinium phosphate draws attention in the chemicals market for its distinct structural features and versatility as a specialty raw material. This compound brings together guanidinium cations and phosphate anions, resulting in a colorless to white crystalline solid. The molecular formula, (C2H7N3)2·H3PO4, reveals two bisguanidinium units paired with a single phosphoric acid molecule. Anyone handling this material soon finds that it behaves much like other powdered inorganic solids—stable under standard conditions, moisture sensitive, and easy to manage when storage conditions remain dry and cool. On the shelf, it often shows up as crystals or fine powder, but processing changes may produce flakes or pearl-like granules. These various forms shape the flow during weighing or measuring, minimizing waste in industrial or research use.
People who work directly with bisguanidinium phosphate notice its density and solubility influence handling and processing routes. The solid has a density in the range of 1.5 to 1.6 g/cm³. Its crystalline structure preserves the integrity of the compound under ambient lab conditions. The molecular arrangement leads to strong ionic bonds, contributing to its stability and resistance to decomposition at room temperature. This property feeds into shelf-life predictions and impacts long-term storage, especially in bulk chemical warehousing. Chemists highlight that this compound dissolves readily in water at room temperature, producing a clear solution, and the resulting phosphate anion gives it mild acid features, a necessary consideration when choosing container materials or anticipating chemical interactions.
Bisguanidinium phosphate resists hazardous reactions under typical laboratory or plant conditions. Still, it deserves care as a chemical: avoid mixing it into solutions containing strong bases, powerful oxidizers, or reducing agents because these combinations may result in unwanted products or hazardous offgassing. Direct skin or eye contact brings moderate irritation risks, typical for phosphates and guanidinium-based compounds. Gloves, goggles, and long sleeves do the heavy lifting on protection in every lab I’ve seen using this material. Even though it doesn’t carry a high-risk classification, regular chemical sense—good ventilation, label checks, thorough documentation—keeps risk to the minimum.
This phosphate shows up commercially under several forms, usually driven by buyer preference and workflow requirements. In most warehouses, you find it as a white powder in sealed bags or a granular solid stored in drums for industrial-scale processes. In the research space, suppliers pack it in smaller, carefully measured vials with guarantees on purity—often 98% or higher. The low hygroscopicity means clumping or caking comes up rarely in storerooms, easing lab work and dosing by weight. Bisguanidinium phosphate features a melting point above 200°C (decomposes before melting), so direct heating during process scaling demands caution to prevent breakdown or unexpected chemical changes.
Shippers and procurement teams need the HS Code for customs and international movement. For bisguanidinium phosphate, suppliers tend to file it under 2835.39, the line for other phosphates of inorganic compounds. Regulatory agencies, including the European Chemicals Agency and REACH, require documentation on signal words, handling instruction sheets, and clear data on immediate hazards or chronic toxicity. REACH and GHS rules push suppliers to share Safety Data Sheets in every shipment, listing everything from ingredients and concentrations to spill response advice and safe disposal methods. No supplier gets by for long without these records—any gap in paperwork slows down shipments or exposes importers to fines.
Synthesizing bisguanidinium phosphate means working with guanidine derivatives and phosphoric acid in precise ratios under controlled pH. These ingredients don’t usually raise big environmental alarms if plant managers ensure effluent controls and treat byproducts properly. Still, all chemical manufacturing faces tougher questions about waste and energy use. Conversations in industry circles today focus on improving water recovery after washing or neutralizing process streams to reduce total dissolved solids before discharge. Facility managers now invest more in inn-line collection and recycling. This forward-looking strategy not only matches environmental expectations, but it cuts operating costs and meets rising plant audit standards imposed by clients and international partners.
Though bisguanidinium phosphate does not reach toxic thresholds seen in alkali phosphates or certain guanidine derivatives, responsible use matters for every handler. Spills on benchtops or floors should get prompt attention with spill kits, and leftover solids need sealing in designated hazardous waste containers. Wastewater from cleaning glassware or equipment containing this chemical gets routed to chemical treatment tanks, not straight into municipal drains. Long-term exposure research shows low bioaccumulation, but standard workplace hygiene—like changing gloves, avoiding food near work areas—makes a difference. Employees trust manufacturers offering up-to-date hazard labels, batch certification data, and clear use instructions, and buyers increasingly ask for full traceability of raw materials back to source mines or key intermediates. This chain of transparency fits strict procurement policies and consumer safety expectations.
Long experience in lab and production shows that bisguanidinium phosphate stands out for reliability, not flash. It contributes as a building block in synthesis routes, often in specialty chemical manufacturing, surface treatments, or catalyst supports. Purity, physical form, and regulatory documentation shape its value, and anyone using it needs familiarity with environmental controls and safety routines. Fact remains—demand for transparency, compliant supply chains, and ongoing improvements in plant efficiency raise the bar for both producers and end users. For chemists, quality managers, and procurement teams, knowing the details of structure and handling forms the base for smart, safe, and productive use of this phosphate salt.
