The Third Foreign Trade Department Of Chemsigma Int. Co., Ltd.

The supplier is based in China and currently lists five active chemical products. Its catalogue is grouped under Laboratory Reagents, Aromatic Chemicals, Industrial Chemicals and Agriculture, reflecting a focus on specialty organic compounds used in research and manufacturing. The product list includes 2-methoxyethyl acetoacetate, Ethyleneglycol monomethyl ether acetate, 5‑Ethylthio‑1H‑Tetrazole (ETT), 4,5‑Dicyanoimidazole and Ethyl 2‑ethylacetoacetate. Each entry is presented without additional branding or client references, aligning with typical imported chemical listings.

The five items are all organic intermediates that fall within the HS chapter 29 range for organic chemicals. They are commonly supplied in analytical‑grade purity for laboratory use, as well as in bulk for industrial processes such as polymer synthesis, agro‑chemical formulation, and pharmaceutical intermediates. The supplier’s catalogue does not specify packaging dimensions, but similar chemicals are usually shipped in 1 L bottles for small‑scale users or 25 kg drums for bulk buyers. No further company history or certifications are mentioned in the provided data.

The catalogue contains two ester compounds (2‑methoxyethyl acetoacetate and Ethyl 2‑ethylacetoacetate), one ether acetate (Ethyleneglycol monomethyl ether acetate), one tetrazole derivative (5‑Ethylthio‑1H‑Tetrazole) and one heterocyclic dicyanoimidazole. In the laboratory chemicals market, such esters are typically offered at ≥99 % purity for analytical grade and ≥95 % for reagent grade, with certificates of analysis confirming the exact purity and water content. Tetrazole and dicyanoimidazole intermediates are often used in click‑chemistry and agro‑chemical synthesis; buyers usually require confirmation of absence of heavy‑metal residues and compliance with REACH‑restricted substances. Industry practice includes offering these products in 1 L amber glass bottles, 5 L PET containers, or 25 kg HDPE drums, depending on order volume.

General industry standards for laboratory reagents call for material safety data sheets (SDS) that meet GHS classification, and many importers request ISO 9001 quality‑management certification from Chinese exporters. Typical specifications for aromatic and industrial chemicals include a melting point range, flash point, and a limit on residual solvents, all documented in the COA. Buyers often look for batch‑to‑batch consistency, which is monitored through HPLC or GC analysis reported in the COA.
