About Tianjin Dongchang Fine Chemical Industry Co., Ltd. - Industrial Chemicals Supplier in China

The supplier is based in China and currently lists five active products in its catalogue. All items fall under the industrial chemicals category and include 4‑acetamidocyclohexanone, Pidotimod, Pramipexole dihydrochloride, P‑toluenesulfonylmethyl isocyanide and Chlormethine HCl. Each product is presented as a separate fine‑chemical item without additional sub‑variants in the public listing. The catalogue does not provide HS‑code references, so the description relies on the chemical names and their typical usage in pharmaceutical intermediates or specialty applications.

The five chemicals are all synthetic organic compounds that are commonly used as active pharmaceutical ingredients (APIs) or as intermediates in drug synthesis. The supplier’s listing reflects a focus on nitrogen‑containing heterocycles, sulfonyl derivatives and halogenated amines, which are typical building blocks for neurological or immunomodulatory agents. No further product specifications such as purity grades or packaging details are supplied in the catalogue.

Product Range and Specialties of Tianjin Dongchang Fine Chemical Industry Co., Ltd.

The catalogue includes 4‑acetamidocyclohexanone, a cyclohexanone derivative used as a chiral building block, usually supplied at ≥98 % purity and packaged in 25 kg drums or 500 kg bulk bags. Pidotimod, an immunostimulant intermediate, is typically offered as a crystalline powder with moisture content below 0.5 % and marketed in 10 kg containers. Pramipexole dihydrochloride, a dopaminergic agent, is normally provided as a hygroscopic solid with a minimum assay of 99 % and shipped in airtight jars or sealed drums. P‑toluenesulfonylmethyl isocyanide, a versatile isocyanide reagent, is generally supplied at ≥95 % purity, low water content, and packed in airtight polyethylene bags. Chlormethine HCl, a nitrogen mustard used in dermatology, is usually delivered as a hydrochloride salt with ≥97 % purity and stored in moisture‑resistant containers. Industry practice for these fine chemicals includes providing a Certificate of Analysis (CoA) for each batch and optional analytical data such as HPLC, NMR or IR spectra.

Trade and Export Information - Tianjin Dongchang Fine Chemical Industry Co., Ltd.

China ranks among the largest exporters of fine organic chemicals, with the majority of shipments classified under HS Chapter 29 (organic chemicals). Buyers from North America, the European Union, and Southeast Asian manufacturing hubs frequently import such intermediates for pharmaceutical formulation. Typical regulatory expectations include compliance with ISO 9001 quality management systems, REACH registration for the EU market, and US FDA cGMP documentation when the chemicals are destined for drug manufacturing. Commonly required documentation comprises a Material Safety Data Sheet (MSDS), a CoA, and, where applicable, a Certificate of Origin. Export logistics from Tianjin often employ FOB Tianjin or CIF major ports, with container loads ranging from 20 ft (≈15 tons) to 40 ft (≈30 tons) depending on the product’s bulk density and packaging.

Sourcing from Tianjin Dongchang Fine Chemical Industry Co., Ltd. - Buyer Guidance

When evaluating a supply source for any of the listed chemicals, request the latest batch CoA, full MSDS, and, if the end market requires, evidence of REACH registration or FDA cGMP compliance. Verify the stated purity (generally ≥95 %) against the analytical method used (e.g., HPLC, GC‑MS) and confirm moisture or residual solvent limits that match industry specifications. Buyers should also clarify packaging options, minimum order quantities (often 5  -  10 kg for specialty intermediates) and lead times, which can vary from 4 to 8 weeks for custom synthesis or bulk release.

What types of chemical intermediates does Tianjin Dongchang Fine Chemical Industry Co., Ltd. list?

The supplier lists five fine‑chemical intermediates: 4‑acetamidocyclohexanone, Pidotimod, Pramipexole dihydrochloride, P‑toluenesulfonylmethyl isocyanide and Chlormethine HCl, all under the industrial chemicals category.

Are Certificates of Analysis available for these products?

Standard industry practice for fine chemicals is to provide a CoA for each batch; buyers should request the CoA together with the MSDS before confirming any order.

Which purity levels are typical for the listed chemicals?

Typical commercial grades range from 95 % to 99 % assay, with moisture content generally below 0.5 % for solid intermediates.

What documentation is required for export to the EU?

EU importers usually require a CoA, MSDS, and proof of REACH registration or an exemption certificate for each chemical.

What are common packaging formats for these fine chemicals?

Bulk quantities are often shipped in 25 kg drums, 500 kg bulk bags, or sealed polyethylene bags, depending on the material’s stability and moisture sensitivity.

Which incoterms are typically used for shipments from Tianjin?

Suppliers from Tianjin frequently quote FOB Tianjin or CIF major destination ports; the choice depends on the buyer’s logistics preferences.

What are the typical lead times for these products?

Lead times vary by product and batch size but generally fall between four and eight weeks for standard bulk releases.

Which markets commonly import these types of chemicals?

North America, the European Union and Southeast Asian pharmaceutical manufacturing regions are the primary import markets for Chinese fine‑chemical intermediates.
