For procurement managers and research scientists in the chemical and pharmaceutical industries, sourcing high-quality raw materials is paramount. 4-Nitrophenylhydrazine Hydrochloride (CAS 636-99-7) is a critical fine chemical used in various synthetic processes and research applications. When looking to buy this compound, understanding the market, particularly from manufacturers and suppliers in China, is key to securing both quality and competitive pricing.

Why Source 4-Nitrophenylhydrazine Hydrochloride?

4-Nitrophenylhydrazine Hydrochloride is recognized for its utility as a chemical intermediate and reagent. Its molecular structure, featuring a nitro group and a hydrazine moiety, makes it valuable in the synthesis of heterocyclic compounds, dyes, and potentially in pharmaceutical research, including areas exploring anticancer activities. Its CAS number, 636-99-7, is a universal identifier that ensures you are sourcing the correct chemical entity.

Key Considerations When Buying: Purity and Specifications

When evaluating suppliers for 4-Nitrophenylhydrazine Hydrochloride, purity is a primary concern. Manufacturers typically offer this chemical with a purity level of 98% or higher, often verified by HPLC (High-Performance Liquid Chromatography). Specifications such as melting point (typically 205-207°C), molecular formula (C6H8ClN3O2), and appearance (often described as a brown to reddish-brown crystalline powder) are crucial for confirming product quality. Always request a Certificate of Analysis (CoA) from your prospective manufacturer or supplier to verify these details.

Finding Reliable Suppliers in China

China is a major hub for chemical manufacturing, offering a wide array of suppliers for 4-Nitrophenylhydrazine Hydrochloride. When selecting a supplier, consider factors beyond just the price. Look for manufacturers with established quality management systems, such as ISO certifications, and a track record of consistent supply and good customer service. Companies specializing in fine chemicals and pharmaceutical intermediates are often the most reliable sources. Engaging with a manufacturer directly can provide better pricing and more direct communication regarding product specifications and custom needs.

Understanding Pricing and Bulk Orders

The price of 4-Nitrophenylhydrazine Hydrochloride can vary based on purity, quantity, and the specific supplier. For larger, bulk purchases, manufacturers are generally able to offer more attractive per-unit pricing. Procurement managers should always request a formal quote, clearly stating the required quantity, purity, and delivery terms. Exploring multiple suppliers and comparing their quotes is a standard practice to ensure you are getting the best value. Remember that factors like MOQs (Minimum Order Quantities) and packaging options can also influence the overall cost and feasibility of a purchase.

The Procurement Process

Once you have identified potential suppliers, the next step is to initiate contact. Typically, this involves submitting an inquiry through their website, providing your company details, the product required (4-Nitrophenylhydrazine Hydrochloride, CAS 636-99-7), and the quantity. Reputable manufacturers will respond promptly with a quotation and information on payment terms, lead times, and shipping. Building a strong relationship with a trusted chemical manufacturer is essential for ongoing supply chain stability and efficient operations.

If you are looking to buy 4-Nitrophenylhydrazine Hydrochloride, focusing on established manufacturers and suppliers in China who prioritize quality and offer competitive pricing for bulk orders will lead to successful procurement. For your chemical needs, consider sourcing from a dedicated manufacturer to ensure consistent quality and reliable supply.
