CAS 108-21-4

Isopropyl Acetate, abbreviated as IPAC, has CAS No.108-21-4 and the molecular formula C₅H₁₀O₂. It belongs to the esters subclass of organic chemicals. At ambient temperature, it is a colourless, clear volatile liquid with a mild fruity odour. This low-molecular-weight ester is partially soluble in water and fully miscible with alcohols, ethers and most common organic solvents. It is flammable; its vapours are heavier than air and can form explosive mixtures with air. It has low corrosivity and good compatibility with most resin systems. Thanks to its moderate evaporation rate and strong solvency for many polymers, it is widely used as an efficient solvent for coatings, printing inks, adhesives and pharmaceutical extraction across various industrial sectors.

Industrial-grade Isopropyl Acetate from Shandong Xima Supply Chain is a trusted ester solvent feedstock for coating manufacturers, ink producers and pharmaceutical extraction facilities worldwide. Its core characteristic comes from its ester structure, which balances volatility and solvency power. Compared with ethyl acetate, it evaporates more slowly and performs better in high-solid resin formulations. It also dissolves nitrocellulose, acrylic resins and synthetic binders effectively. This property helps form stable films and reduces surface defects during coating and ink application. Operators must pay close attention to its flammability and volatility. Adequate ventilation, explosion-proof electrical equipment and static control measures are required during all transfer and handling operations.

A key advantage of our isopropyl acetate is tight control over critical trace impurities, including water content, free acid and heavy-metal residues. Excess moisture or free acid may cause ester hydrolysis during storage, reduce solvent stability and compromise coating curing or extraction purity. Our industrial-grade material keeps these undesirable trace components within narrow technical specifications, verified by gas chromatography and Karl-Fischer moisture testing. In addition, it mixes well with other co-solvents to support flexible formulation adjustments, removing extra purification steps for plant-scale blending and extraction workflows.

Buyers gain tangible operational and commercial benefits by choosing our reliable isopropyl acetate supply. Strictly controlled impurity and moisture levels stabilise coating formulation quality and lower reject rates for finished ink and coating products, cutting raw-material losses and production costs on client production lines. Our flexible bulk inventory supports both long-term framework contracts and urgent spot orders for coating, ink and fine-chemical manufacturers. Customers can maintain continuous production cycles without frequent supplier changes. Every shipment comes with complete official documentation to facilitate import customs clearance and internal quality audits for overseas industrial enterprises.

These performance claims are backed by our strict supply chain control protocols. Each batch of isopropyl acetate is sampled representatively and tested in our in-house laboratory before dispatch. Test parameters include GC assay purity, visual appearance, Karl-Fischer water content, acidity and heavy-metal levels. All test results are recorded on each lot's Certificate of Analysis. Our isopropyl acetate has been exported for coating formulation, printing ink production and pharmaceutical extraction projects, earning repeat orders from industrial end users. We only source material from audited upstream manufacturers holding valid hazardous chemical production permits to ensure consistent raw material quality.

Global chemical buyers often have concerns about purity drift, rising acid values during storage, fire hazards, incomplete hazard documentation and unstable delivery schedules for flammable volatile ester solvents. As a licensed hazardous chemical supply chain trader, Shandong Xima conducts comprehensive pre-shipment inspections for every isopropyl acetate consignment. We hold sufficient safety stock for standard industrial-grade specifications to meet urgent procurement demands. A full document package containing GHS-compliant MSDS, batch-specific COA, commercial invoice and packing list is prepared to satisfy customs compliance requirements. Our technical support team can share practical best practices for sealed cool storage, explosion-proof transfer procedures and PPE guidance to help on-site plant operators handle this flammable ester solvent safely.
