Suzhou Stone Lake Pharma Tech Co., Ltd.

Based in Suzhou, China, Suzhou Stone Lake Pharma Tech Co., Ltd. lists five active chemical products. The catalogue includes 4-(Trifluoromethyl)-1H-imidazole, 2,1,3‑Benzothiadiazole, 4,7‑DIBROMO‑2,1,3‑Benzothiadiazole, N‑Boc‑Nortropinone and 2,4,6‑Trichlorobenzoic acid. These compounds are classified under aromatic chemicals, agricultural chemicals and laboratory chemicals in the supplier’s top categories. Each entry is identified by its chemical name without additional packaging or grade details in the public data. The supplier is categorized as an imported tier with a harbor trust rating.

The listed molecules are heterocyclic or halogenated organics commonly used as intermediates in synthesis of agro‑chemicals, pharmaceuticals and research reagents. For example, 4-(Trifluoromethyl)-1H-imidazole serves as a fluorinated building block, while benzothiadiazole derivatives are employed in dye and pesticide development. N‑Boc‑Nortropinone is a protected tropane precursor used in medicinal chemistry. 2,4,6‑Trichlorobenzoic acid functions as a chlorinated aromatic acid for polymer and resin applications. All five items fall within HS Chapter 29 for organic chemicals, which is the typical tariff classification for such substances.

The catalogue covers five organic intermediates that belong to the aromatic and heterocyclic chemical families. In the market, such compounds are offered in analytical grade (purity ≥ 98 %) and research grade (purity ≥ 95 %) specifications, with the higher grade required for pharmaceutical synthesis. Common material forms include solid powders or crystalline solids that are moisture‑sensitive and stored under inert atmosphere. Buyers often receive these chemicals in sealed polymer bottles or fiber drums, depending on order size.

Industry standards for these chemicals include compliance with the Global Harmonized System (GHS) for labeling and safety data sheets, as well as adherence to REACH registration for EU imports. Quality control typically involves HPLC, GC‑MS or NMR verification, and certificates of analysis must state assay, impurity profile and water content. For agricultural applications, the same intermediates may need to meet additional pesticide‑active‑ingredient regulations such as ISO 9001‑based manufacturing processes.
