Material monobenzone

For B2B procurement, Monobenzone must typically meet a purity level of ≥99% as determined by HPLC (High-Performance Liquid Chromatography). It is a white to off-white crystalline powder. Buyers should verify the Melting Point (117°C to 120°C) and ensure the Loss on Drying is ≤0.5%. Always request a Certificate of Analysis (COA) for every batch to confirm these chemical properties.

As a chemical substance used in pharmaceuticals and cosmetics, suppliers should ideally hold ISO 9001:2015 for quality management. Depending on the target market, compliance with REACH (EU) or TSCA (USA) is essential. Furthermore, the supplier must provide a comprehensive Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) that complies with the GHS (Globally Harmonized System) to ensure safe handling and transport.

Monobenzone is primarily used as a topical depigmenting agent in the pharmaceutical industry, specifically for treating vitiligo to permanently depigment normal skin surrounding vitiliginous lesions. It is also utilized as an intermediate in organic synthesis and in the production of certain rubber chemicals as an antioxidant. Buyers must ensure the grade (Medical vs. Industrial) matches their specific application.

Monobenzone is sensitive to light and air. It should be stored in tight, light-resistant containers (typically double-layered PE bags inside fiber drums). The storage environment must be cool (below 25°C), dry, and well-ventilated. Exposure to moisture or direct sunlight can lead to oxidation, which compromises the efficacy and color of the raw material.

Utilize secure payment methods and trade assurance services. On Made-in-China.com, you can look for Audited Suppliers who have undergone third-party verification by companies like SGS or Bureau Veritas. This reduces the risk of fraud and ensures the supplier is a legitimate manufacturing or trading entity.

Monobenzone is generally not classified as a highly dangerous good for transport, but it is a chemical powder. You must ensure the supplier provides a 'Transport of Chemical Goods' certificate to avoid customs delays. For shipping to countries like the US or Europe, ensure the HS Code (typically 290729) is correctly declared to determine accurate customs duties and import taxes.

Price is heavily influenced by order volume and raw material market fluctuations. For orders exceeding 100kg, you should negotiate for a 5-10% volume discount. Additionally, discuss long-term supply contracts to lock in prices, as the chemical market can be volatile. Always clarify if the quoted price is FOB (Free On Board) or CIF (Cost, Insurance, and Freight) to avoid hidden logistics costs.

Always follow a 'Sample First' policy. Order a small sample (e.g., 10-50g) for independent lab testing before committing to a bulk purchase. For large-scale orders, consider hiring a third-party inspection service to perform a pre-shipment inspection (PSI) at the supplier's warehouse to verify quantity, packaging, and batch consistency.
