For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing reliable, high-purity raw materials is paramount. Among these, n-Docosanol, identified by CAS 661-19-8, stands out due to its dual utility as an effective antiviral agent and a versatile cosmetic ingredient. This article serves as a guide for buyers looking to purchase n-Docosanol, focusing on its applications, quality considerations, and how to identify trusted manufacturers and suppliers, particularly those based in China.

n-Docosanol, also known as behenyl alcohol, is a C22 saturated fatty alcohol. Its unique molecular structure lends itself to a range of beneficial properties. Medically, it is recognized for its ability to inhibit the replication of the herpes simplex virus (HSV), making it a key component in topical treatments for cold sores. For cosmetic formulators, its role as an emollient, binder, and emulsion stabilizer is invaluable. It enhances skin feel, improves product stability, and increases viscosity, contributing to a superior user experience in creams, lotions, and other personal care products.

When considering a purchase, understanding the product's specifications is crucial. Key attributes to look for include its melting point (typically 65-72°C), chemical formula (C22H46O), and purity. Buyers often seek pharmaceutical-grade or cosmetic-grade n-Docosanol, depending on their application. Ensuring the supplier can provide a Certificate of Analysis (CoA) detailing these specifications is a fundamental step in verifying product quality.

Identifying a reliable manufacturer and supplier is equally important. For businesses operating globally, China has emerged as a significant hub for chemical manufacturing, offering competitive pricing and substantial production capacities. When searching for an n-Docosanol supplier in China, it is advisable to look for companies that emphasize quality control, adherence to international standards (such as ISO certification), and possess a strong track record in the fine chemical and pharmaceutical raw materials sector. Companies that offer transparent communication, efficient logistics, and responsive customer service are typically preferred.

For R&D purposes, smaller quantities might be needed, while large-scale manufacturing requires bulk purchasing power. A good supplier will cater to various order sizes. Furthermore, inquiries about packaging options, minimum order quantities (MOQs), payment terms (e.g., L/C, T/T, Paypal), and Incoterms (e.g., FOB, CFR, CIF) are essential parts of the procurement process. Obtaining a price quote early in the sourcing phase will also help in budgeting and supplier evaluation.

In summary, sourcing high-purity n-Docosanol involves understanding its applications, meticulously checking product specifications, and selecting a dependable manufacturer and supplier. For businesses looking to buy n-Docosanol, especially from China, prioritizing quality, reliability, and competitive pricing will ensure the successful integration of this versatile chemical into their products. Whether for antiviral drug development or advanced cosmetic formulations, a strategic procurement approach guarantees optimal results.
