For businesses operating in the fine chemical, cosmetic, and pharmaceutical industries, the procurement of key intermediates is a critical operational function. 4,5-Diamino-1-(2-Hydroxyethyl)Pyrazole Sulfate (CAS 155601-30-2) is one such compound, valued for its role in sophisticated chemical processes. This guide aims to equip potential buyers with the knowledge to effectively source this important intermediate, focusing on critical quality parameters and supplier selection.

The primary consideration when purchasing 4,5-Diamino-1-(2-Hydroxyethyl)Pyrazole Sulfate is its purity. The assay level, commonly determined via HPLC, dictates the compound's effectiveness and reliability in downstream applications. A purity of ≥99.0% is generally considered high-grade and is essential for applications demanding precision, such as pharmaceutical synthesis or advanced cosmetic formulations. Impurities can lead to unpredictable reaction outcomes, compromise product quality, and potentially introduce safety concerns.

Beyond assay, several other specifications require close attention. Moisture content, often quantified as 'Loss on Drying', should be minimal to ensure stability and accurate material handling; limits of ≤1.0% are common. Similarly, ash content, representing inorganic residues, should also be low (≤1.0%), indicating a cleaner, more refined product. The presence of trace metals, like iron (often specified at ≤50 ppm), can be critical, especially for pharmaceutical intermediates where metal contamination is strictly regulated.

When looking to buy, identifying a reputable manufacturer and supplier is paramount. Established companies can provide consistent product quality, robust documentation (such as Certificates of Analysis detailing all specifications), and reliable supply chains. For buyers sourcing internationally, particularly from major chemical manufacturing regions like China, due diligence in selecting suppliers is crucial. Companies with a proven track record in quality control and export can offer both competitive pricing and assurance of compliance with international standards.

The packaging and storage of 4,5-Diamino-1-(2-Hydroxyethyl)Pyrazole Sulfate are also important aspects. Typical packaging in 25 kg drums protects the product during transit and storage. Proper storage conditions, such as keeping the material in a cool, ventilated place, help maintain its intended quality and shelf life.

Whether you are a cosmetic chemist developing new hair colorants or a pharmaceutical researcher working on novel drug synthesis, securing a high-quality supply of 4,5-Diamino-1-(2-Hydroxyethyl)Pyrazole Sulfate is a foundational step. By focusing on stringent specifications and partnering with trustworthy manufacturers, businesses can ensure the success of their development and production efforts.
