For procurement managers and R&D scientists in the chemical and pharmaceutical industries, identifying reliable suppliers for key raw materials is a continuous challenge. Among the essential intermediates, 4-Chlorophthalic Acid Monosodium Salt (CAS: 56047-23-5) stands out for its significant applications in pigment and anhydride synthesis. This guide aims to assist buyers in navigating the process of sourcing this compound, emphasizing quality, price, and supplier reliability.

The primary driver for purchasing 4-Chlorophthalic Acid Monosodium Salt is its role as a precursor. It is a critical intermediate for producing phthalocyanine blue pigments, renowned for their exceptional color and durability, and chlorophthalic anhydride, used in a wide range of industrial chemicals. When you are looking to buy this compound, understanding its specifications is paramount. Typically, it is supplied as a white to yellowish-brown powder with an assay requirement of ≥73%. Ensuring this purity level is crucial for the success of downstream synthesis reactions.

When evaluating potential suppliers, particularly those based in China, it’s important to look for manufacturers with a proven track record. Companies like NINGBO INNO PHARMCHEM CO.,LTD. offer this intermediate, emphasizing consistent quality and competitive pricing. Factors to consider include the supplier’s production capacity, adherence to quality standards (such as ISO certifications), and their ability to provide comprehensive documentation, including Certificates of Analysis (CoA). A good manufacturer will also offer competitive price points, making your procurement more cost-effective.

The supply chain for chemical intermediates can be complex. Therefore, selecting a supplier that guarantees reliable delivery and responsive customer service is essential. Look for manufacturers who can provide flexibility in order quantities, from laboratory scale to bulk industrial orders. Understanding the typical packaging (e.g., 25kg/bag) and recommended storage conditions (cool, dry, dark) will also help in maintaining the product’s integrity upon arrival.

For businesses in need of 4-Chlorophthalic Acid Monosodium Salt, conducting thorough due diligence on potential manufacturers is a worthwhile investment. Comparing quotes, checking supplier reviews, and even requesting samples can help ensure you partner with a manufacturer that meets your quality and logistical requirements. By focusing on these key aspects—product purity, price competitiveness, and supplier reliability—buyers can effectively source this vital chemical intermediate and support their manufacturing objectives.
