Bis(5-Oxo-L-Prolinato-N1,O2)Zinc steps into the world of specialty chemicals with a structure that gets both chemists and manufacturers thinking. As the name suggests, its backbone carries zinc coordinated by two 5-oxo-L-prolinato ligands binding through nitrogen and oxygen atoms. The full structure gives this compound a complexity not found in more common zinc salts. Anybody reading a material safety datasheet or sifting through product options in a laboratory catalog spots it as something more specialized than zinc oxide or basic zinc carbonate. Its chemical formula, C10H12N2O6Zn, tells a story of five-membered rings featuring carboxyl and keto groups—all arranged around a single zinc core. Judging by the molecular heft and the way the ligand binds, this is no lightweight additive.
Physical characteristics stick out, even for folks who rarely handle raw chemical materials. Bis(5-Oxo-L-Prolinato-N1,O2)Zinc comes mainly as a solid. It often turns up in the form of crystalline powder, though flakes or small pearls crop up depending on how the batch crystallizes and dries. No matter how close you look, it won’t show up as a typical granular or amorphous material; those crystals catch the eye and signal a high level of purity and proper synthesis conditions. Under good light, some batches reflect a faint sheen, which hints at uniformity in the lattice. Most measurements peg the density between 1.7 and 1.9 grams per cubic centimeter, giving it a solid feel when scooped or weighed for laboratory prep. It remains stable at room temperature and holds up well in dry storage. Water does not dissolve it easily, but some solvents may break those bonds if conditions call for it. In terms of color, expect a white to off-white shade, making it stand out against other zinc complexes that lean gray or yellow.
For those deep in chemical engineering or research, Bis(5-Oxo-L-Prolinato-N1,O2)Zinc rings a few bells for its stability compared to simple zinc salts. It resists decomposition at temperatures up to 200°C, which means you can count on it in moderate heat processes. This matters in manufacturing, where stability guards against unexpected product changes and possible hazards. Chemically, it holds a neutral to slightly basic pH depending on the presence of outside acid. Its structure blocks a lot of unwanted redox reactions that cheaper zinc materials might allow. It stands out for its relatively low solubility in water and greater compatibility in nonpolar solvents or buffered solutions. Anyone designing blends or solutions for specific industrial tasks would factor in its slow breakdown into zinc and proline derivatives at high heat or extreme pH values. This stability and predictability make it reliable for those who do not want surprises in process or product development.
People ask about why this compound gets shelf space. Bis(5-Oxo-L-Prolinato-N1,O2)Zinc earns respect mainly in the world of research and high-precision manufacturing. In studies focusing on zinc delivery or controlled release, the exact structure makes dosing predictable and helps with specific targeting in biomedical applications. Its high purity and unique solubility pattern allow formulators in pharmaceuticals, advanced materials, and catalysis to push boundaries beyond what more basic zinc raw materials can manage. Specialist companies appreciate its ability to deliver zinc without unwanted ions or contaminants. Precise work in organic synthesis and coordination chemistry leans on its stability and reproducibility, making it a “go-to” choice where control matters more than cost. Some niche industrial processes also use its reliable structure to introduce zinc without causing side reactions or breakdown products that would muddy the process stream. Its tight association with emerging technologies and research means that market value holds steady, if not high, compared to bulk zinc compounds.
Chemical safety officers pay close attention to compounds like this, knowing that specialty chemicals sometimes present less obvious dangers. Bis(5-Oxo-L-Prolinato-N1,O2)Zinc does not act aggressively toxic but demands respect partly due to its zinc content. Inhalation of fine powder or direct contact with moist skin over long periods risks mild irritation in susceptible people. Safety data identifies it as a mild irritant rather than an acute toxicant. Like with all laboratory materials, users rely on gloves, dust masks, and goggles to keep exposure low. Storage in tightly sealed containers, away from moisture and reactive chemicals, prevents caking or contamination. Waste disposal follows standard chemical waste rules for transition metals and organics—avoiding drains and mixing with incompatible substances. Overexposure in confined spaces such as powder rooms or tight synthesis labs sometimes prompts headaches or nausea, especially if baseline ventilation lacks. The product’s MSDS outlines safe working concentrations, which most research users follow closely. For larger material transfers in the factory or warehouse, good local exhaust and careful scale-up keep risk low.
Global commerce sorts all chemicals with HS (Harmonized System) codes. Bis(5-Oxo-L-Prolinato-N1,O2)Zinc commonly travels under codes reserved for organic zinc compounds, with regional variations on the specific 6- or 8-digit numbers. For importers and customs agents, the main challenge comes from proving purity, composition, and intended use, which affects tariffs and regulatory checks. Certificates of analysis and specification sheets detail not just zinc content but trace impurities, crystal form, free proline, and moisture level. Buyers usually demand at least 98% purity and tight limits on residual solvents before importing large quantities. Shipments move in double-lined drums, pails, or interior-bagged cartons, keeping the powder dry and avoiding cross-contamination during international transit. Tracking batches by lot and keeping a clear audit trail helps with recalls or regulatory queries down the road. For operators, these codes and certificates are not just a formality; they safeguard product integrity and legal compliance.
