For procurement managers and R&D scientists in the pharmaceutical, nutraceutical, and cosmetic industries, sourcing high-quality Resveratrol (CAS 501-36-0) is a critical task. The efficacy and safety of final products directly depend on the purity and reliability of the raw materials. This guide aims to assist buyers in understanding the key considerations when purchasing Resveratrol powder, particularly when sourcing from China.

The most important factor when you buy Resveratrol is its purity. Aim for a minimum of 99% purity to ensure optimal benefits and compliance with industry standards. Reputable manufacturers will provide a Certificate of Analysis (CoA) detailing the purity, molecular weight, and other critical specifications. Always request this documentation before making a purchase. Understanding that Resveratrol is commonly derived from sources like Polygonum Cuspidatum or grape skins can also help in evaluating product quality.

Ensuring safe and hassle-free delivery is another significant concern. Many experienced Chinese chemical suppliers offer a '100% pass customs' guarantee for major global markets, including the USA, Canada, and Europe. This assurance is invaluable, as it mitigates the risk of delays or confiscation at customs. Furthermore, reliable suppliers utilize robust packaging methods and work with trusted shipping partners to ensure products arrive safely, typically within 7-15 days. This logistical expertise is a key differentiator.

When selecting a supplier, consider their overall service package: competitive pricing for bulk orders, responsive customer support, and a commitment to long-term relationships.
