n-Butanol 99.5% Prime Grade (C₄H₁₀O), also known as n-Butyl Alcohol, is a high-purity, colorless liquid with a characteristic alcohol-like odor and excellent solvent properties. Widely used in paints, coatings, and chemical manufacturing, it serves as an intermediate in the production of butyl acrylates, glycol ethers, and plasticizers. Its controlled evaporation rate and strong solvency enhance formulation performance in coatings, inks, and cleaners. Trusted across chemical processing, coatings, and industrial manufacturing sectors for its purity, consistency, and reliable performance.

Typical U.S. classification for this product: label elements under OSHA’s Hazard Communication Standard (29 CFR 1910.1200) and transport under U.S. DOT (49 CFR 172.101), compiled from manufacturers’ safety data sheets and harmonised GHS classifications, checked October 2026. Environmental hazards are shown for information; the OSHA label does not cover them. Classification can differ by supplier, grade and concentration: the supplier’s U.S.-format SDS, sent with your quote, is the governing document.
Readily dissolves complex resins, polymers, and heavy greases.
Tailored evaporation rates to ensure smooth finishes in paints and coatings.
Maximizes yield in chemical and botanical extraction processes.
Acts as an excellent coupling agent to blend incompatible ingredients.
Evaporates cleanly without leaving residues, ideal for precision cleaning.
We find the right Indian manufacturer for your grade, quantity and target price. Around that, use the services you need:
Before we recommend a manufacturer, we check it in five layers: its documents (COA, SDS, certifications), its business license and IEC status with India’s DGFT, its standing with our industry contacts, an in-person visit to the facility, and its export record.
Want proof that the batch matches its COA before it ships? We collect samples at the factory or port and coordinate testing for purity, grade and contaminants at accredited third-party laboratories. Lab fees are passed through at cost.
We coordinate the paperwork (commercial invoice, packing list, certificate of origin, bill of lading, SDS and COA), compliant packaging and labeling, and the freight forwarder, from export clearance in India to customs entry in the U.S., as your one point of contact.
Our American-led team in India can be at a supplier’s site, check its machinery and real capacity, sit in on negotiations and review documents in person, then report back to you directly, with photos and video from the factory floor.
Going the other way? If you make a specialty chemical or industrial product and want to sell it in India, we provide the on-ground presence and industry network to open that market.
Consistent quality and international standards.
Bulk availability with on-time delivery.
Flexible packaging options as per requirement.
Technical guidance and dedicated customer support.
