Shenyang East Chemical Science-Tech Co., Ltd.

In the global fine chemical and pharmaceutical raw material market, polyethylene glycol has become one of the most indispensable pharmaceutical excipients, favored by pharmaceutical manufacturers and chemical purchasers for its non-toxicity, excellent biocompatibility and stable chemical properties. As a professional chemical supplier, we supply high-purity PEG products customized for pharmaceutical auxiliary materials, covering diversified specifications to meet the production demands of different pharmaceutical dosage forms.

Dicyclohexylamine (CAS 101-83-7), also known as N-Cyclohexylcyclohexylamine, is a high-value aliphatic cyclic amine compound. At room temperature, it appears as a colorless to pale yellow viscous liquid with a characteristic amine odor, miscible with water, ethanol, and most organic solvents. Renowned for its strong alkalinity, excellent complexation ability, and chemical stability, Dicyclohexylamine serves as a critical intermediate for unsaturated polyester resins and agrochemical synthesis, while also acting as a core additive in metalworking fluids. For chemical procurement professionals, Dicyclohexylamine and its synergistic agent Dodecyldiphenylamine deliver unmatched performance in lubrication, rust inhibition, and fluid stability, making them indispensable for industrial formulation optimization.

When a repair task involves historic materials, delicate surfaces, or strict contamination limits, the cleaning solvent must do more than remove residue—it must stay clean. At East Chemical, we supply ultra‑high purity γ-Butyrolactone (GBL) designed for high‑control applications where even trace metals can create downstream quality risk. For teams that rely on gamma butyrolactone as a process solvent, purity consistency is non‑negotiable.
