Import Grubbs Catalyst 2nd Generation — Buy in Bulk from Supplier in China

Hangzhou Catalyz Pharmaceutical Co., Ltd. manufactures the second‑generation Grubbs catalyst, identified by CAS 246047‑72‑3 and catalog number 44‑0002. The catalyst is a dark red to dark brown fine powder whose molecular formula is C46H65Cl2N2PRu. Although the molecular weight is not disclosed, the active ruthenium centre provides the metathesis activity characteristic of this catalyst class. The product is produced at the company’s facility in Hangzhou, Zhejiang Province, China.

Typical commercial batches of Grubbs II catalyst are supplied with a purity of 98 % or higher, measured by gas chromatography, and contain less than 0.5 % residual moisture to preserve activity. The powder is moisture‑sensitive and is usually stored under inert nitrogen atmosphere at temperatures between - 20 °C and 25 °C to prevent degradation. Standard packaging consists of sealed amber‑glass ampoules or vacuum‑packed aluminium foil bags, each containing 25 g of catalyst, to maintain stability during transport. Users often require a material safety data sheet and a certificate of analysis with each shipment.

The catalyst is employed in olefin metathesis reactions across pharmaceutical synthesis, polymer modification and fine‑chemical production, making it valuable to contract research organisations and bulk chemical manufacturers. Hangzhou Catalyz offers bulk ordering with flexible minimum quantities, and ships under FOB or CIF terms; payment can be arranged via L/C or T/T as indicated in the profile. Prospective buyers should confirm the exact MOQ, lead time and any required handling certifications before finalising the purchase.

Hangzhou Catalyz Pharmaceutical Co., Ltd. is headquartered at 10R, 13F, Building B, New Yonth Plaza, No.267 Shangtang Road, Hangzhou 310000, Zhejiang Province, China. The supplier carries a harbour‑level trust tier, indicating that its business credentials have been verified on the platform. Its profile shows a 0 % response rate and no recorded average response time, suggesting that communication may need to be initiated proactively. The company focuses on the production and distribution of specialised organometallic catalysts for synthetic chemistry.

The listing does not disclose production capacity, annual turnover or specific quality certifications such as ISO 9001; therefore buyers should request such information during negotiations. While the product description mentions compliance with standard safety data sheet requirements, the supplier should provide the latest MSDS and certificate of analysis for each batch.
