The product is Optical Brightening Agent Ob-1, a bis‑benzoxazole derivative used as a fluorescent brightening agent. It is supplied by Shandong Raytop Chemical Co., Ltd. in powder form with a stated purity of 99 % and can withstand temperatures up to 360 °C. The chemical name is 2.2‑(4‑aminophenyl)‑1,3,5‑triazine and it is commonly packaged in 25 kg drums or 500 kg bulk bags.
As a fluorescent brightener, OB‑1 belongs to the class of high‑performance optical additives that are added to polyester fibres, engineering plastics and polymer resin formulations. In the chemicals industry the typical particle size range is 10‑100 µm and the agent shows high solubility in organic solvents such as dimethylformamide and ethanol. The 99 % purity meets the standard specification for industrial bulk supply and the heat stability to 360 °C exceeds the usual limit of 300 °C for comparable brighteners.
Manufacturers of synthetic fibres, plastic moulders and coating formulators source this additive to improve whiteness and colour vibrancy. Shandong Raytop lists the material for export and states that bulk shipments are arranged in drums or bags, with payment terms of T/T or L/C as commonly negotiated. Buyers should confirm minimum order quantities, incoterms and any required certificates directly with the supplier before placing an order.

Before committing to a purchase, verify that Shandong Raytop Chemical Co., Ltd. holds a valid business licence and matches the harbour trust tier shown in the marketplace. Request a recent Certificate of Analysis that details purity, particle size and any residual solvents. Because the listing does not provide certification details, ask the supplier to supply safety data sheets and any applicable regulatory compliance documents.
Discuss logistics early by confirming the preferred Incoterm, whether FOB Jinan port or CIF Shanghai, and the expected lead time for bulk drums or bags. Clarify the minimum shipment size, as the supplier has not disclosed a MOQ, and arrange freight forwarding arrangements that accommodate the 25 kg or 500 kg packaging. Agree on payment terms such as T/T or L/C and ensure they are reflected in the pro‑forma invoice.
Plan a quality assurance step by organising a third‑party inspection of the powder before loading, focusing on purity, moisture content and particle‑size distribution. Request that the supplier provide a batch‑wise test report and retain samples for in‑house verification of fluorescence performance. Documentation should include a Material Safety Data Sheet, a Certificate of Analysis and any export‑related certificates required by the importing country.
