Import Alcohol Isopropyl — Buy in wholesale FOB from Supplier in China

Alcohol isopropyl, also known as isopropanol or 2-propanol, is a colourless, flammable chemical compound with the formula CH3CHOHCH3. This listing from Dinayen Enterprise Management, based in Nanjing, China, offers this solvent for industrial and pharmaceutical applications. The supplier's source data links to ethanol (CAS 64-17-5, molecular weight 46.06840) in its description, though the listed product is isopropyl alcohol; buyers should verify the exact CAS number and molecular specifications with Dinayen directly. Isopropyl alcohol typically carries CAS 67-63-0 and a molecular weight of 60.10 g/mol, distinguishing it from ethanol by an additional methyl group and markedly different solvent properties.

Standard industrial grades of isopropyl alcohol range from 70% to 99.9% purity, with anhydrous grades requiring careful handling due to hygroscopicity. The material is produced by hydration of propylene, either via the direct or sulfuric acid process, yielding pharmaceutical, reagent, or technical grades depending on purification levels. Typical contaminants in lower grades may include acetone, water, and trace propanol isomers; pharmaceutical and electronic grades demand tighter control on organics and particulates. Storage requires sealed containers away from oxidisers, with ventilation to prevent vapour accumulation above the flammability limit of 2% to 12% in air.

Pharmaceutical manufacturers use isopropyl alcohol as a disinfectant and antiseptic base, while electronics firms employ anhydrous grades for semiconductor cleaning and degreasing. Cosmetics and personal care formulators value its rapid evaporation and low residue, and industrial coatings producers use it as a solvent and diluent. Buyers should confirm with Dinayen Enterprise Management whether the offered grade meets USP, EP, or ACS specifications, as the source description does not state purity levels or accompanying certificates of analysis. The supplier's location in Nanjing, Jiangsu Province, places it within China's established chemical manufacturing corridor, though its response rate is currently zero and average response time is unrecorded.

Dinayen Enterprise Management is registered at 1842, Building E07, Suning Wisdom Valley, No.272 Iqingmen Avenue, Gulou District, Nanjing, 210019, China. The supplier holds a Harbor trust tier on the platform, with a response rate of 0.00 and no recorded average response hours. These signals indicate limited or no engagement with buyer enquiries through the platform channel, so direct contact via the provided Nanjing address may prove more reliable for urgent procurement discussions.

The listing conflates product descriptions between ethanol and isopropyl alcohol, which raises questions about catalogue management accuracy. No certifications, production capacity figures, or export licence details are stated in the source material. Buyers should request a current product specification sheet, certificate of analysis for a recent batch, and confirmation of the supplier's actual manufacturing or trading status before committing to volume orders.
