Zoupingmingxing Chemical Ltd.

Zoupingmingxing Chemical Ltd. is based in China and currently lists five active products. The catalogue covers three chemical segments: industrial chemicals, laboratory chemicals and cosmetic chemicals, and the five entries are N‑(4‑cyano‑phenyl)‑glycine, (1s)‑1‑phenyl‑1,2,3,4‑tetrahydroisoquinoline, Ethyl 1‑benzylpiperidine‑4‑carboxylat, 2‑[1‑(mercaptomethyl)cyclopropyl]acetic acid and 2‑amino‑2,3‑dimethylbutyramide. All five compounds belong to the organic‑chemical families that are classified under HS Chapter 29 for organic chemicals. The supplier’s listing does not include any additional product lines beyond these five items.

The five compounds are presented without accompanying specifications, but each falls into a class of intermediates commonly used for synthesis of pharmaceuticals, specialty polymers or cosmetic actives. The catalogue does not state purity levels, but typical industrial‑chemical intermediates of this type are supplied at 95‑99 % purity and are shipped in bulk containers or drums. Zoupingmingxing Chemical Ltd. does not disclose any certifications in the supplied data, so buyers should verify compliance documents separately.

The product list consists of heterocyclic and aromatic intermediates that are frequently required in fine‑chemical synthesis. N‑(4‑cyano‑phenyl)‑glycine and 2‑amino‑2,3‑dimethylbutyramide are amino‑acid analogues often used as building blocks for active‑pharmaceutical‑ingredient (API) routes, typically demanded at ≥98 % purity and moisture ≤0.5 %. (1s)‑1‑phenyl‑1,2,3,4‑tetrahydroisoquinoline and Ethyl 1‑benzylpiperidine‑4‑carboxylat are nitrogen‑containing heterocycles that appear in medicinal‑chemistry libraries; they are usually supplied with documented melting points and optical rotation data. 2‑[1‑(mercaptomethyl)cyclopropyl]acetic acid is a sulfur‑functionalised acid employed in agro‑chemical and polymer precursors, where acid value and sulfur content are standard quality metrics. In the broader market, buyers of such intermediates request certificates of analysis (CoA), safety data sheets (SDS) and, where applicable, batch‑level analytical reports such as HPLC or NMR spectra.
