Import 1,3-Dibromo-5,5-Dimethylhydantoin (Dbdmh) — Buy in Bulk from Supplier in China

Shandong Angel Chemical Co., Ltd. supplies 1,3-dibromo-5,5-dimethylhydantoin (DBDMH, CAS 77-48-5) from its facility in the Binhai Development Zone, Weifang, Shandong. This bromine-based oxidising biocide is a white to off-white crystalline powder with a molecular weight of 285.94 g/mol (C5H6Br2N2O2). It dissolves in chloroform and ethanol, has limited solubility in water, and remains stable when dry but decomposes in strong acid or alkali. The supplier's own quality standard sets the top-grade purity at a minimum of 98.0% DBDMH content and 54.79% bromine (as Br2), with a maximum volatile matter of 0.50%.

DBDMH is used widely as a biocide for disinfecting industrial circulating water systems, swimming pools, springs, hospital wastewater, and aquaculture operations. It also finds application in food processing facilities, hotels, warehouses, and epidemic control zones. Beyond water treatment, the chemical serves as a brominating agent in the chemical, pharmaceutical, and rubber industries. Shandong Angel Chemical packs the product in 40 kg cartons lined with double-layer plastic bags, or can accommodate custom packaging on request. Buyers should confirm current pricing, minimum order quantity, and lead times directly with the supplier.

Shandong Angel Chemical Co., Ltd. is based in the Binhai Development Zone, Weifang, Shandong Province, China. The company manufactures and supplies DBDMH and related water treatment chemicals from this location. Its listed response rate and average response time are currently at zero, which may indicate a new or recently inactive profile on the platform. Buyers are advised to send detailed enquiry messages and allow additional time for a reply, or to follow up through alternative contact channels if available.

The supplier's product data includes a two-tier quality classification (top-grade and qualified) with defined purity and bromine specifications, suggesting in-house production or direct access to manufacturing. Storage and handling guidance accompanies the product, advising cool, dry conditions and separation from toxic substances.
