For procurement managers, R&D scientists, and product formulators in the chemical and agricultural sectors, understanding product specifications is paramount to making informed purchasing decisions. Basic Copper Sulfate, a critical inorganic compound, is no exception. This article, from the perspective of a leading China-based manufacturer and supplier, aims to demystify the key specifications of Basic Copper Sulfate and guide you on how to secure a reliable supply at a competitive price.

At its core, Basic Copper Sulfate is identified by its molecular formula, CuSO4·3Cu(OH)2, and a molecular weight of 452.29. Its physical appearance is a green monoclinic crystal, notable for its minimal solubility in water but good solubility in dilute acids and ammonia. However, the true value for B2B buyers lies in the detailed specifications that differentiate product grades and guarantee performance. When you are looking to buy Basic Copper Sulfate, pay close attention to the following indicators:

Purity and Content: This is often expressed as a minimum percentage. For industrial applications, a content of ≥98% is typical, while agricultural grades might specify ≥96%. This indicates the proportion of the active compound, directly impacting its efficacy. As a manufacturer, we ensure these purity levels are consistently met through rigorous quality control.

Copper Content: While related to overall purity, specific copper content is vital, especially for applications where copper's catalytic or biocidal properties are key. The source material often provides a reference for this, and it's a critical factor for formulators to consider.

Insoluble Matter: A low percentage of insoluble matter (e.g., ≤0.2%) is desirable. High insoluble content can indicate impurities that may hinder application or reduce the effectiveness of the formulation. As a supplier, we prioritize minimizing these inert substances.

Impurity Levels: Critical impurities include Iron (Fe), Nitrate (NO3), Arsenic (As), Chloride (Cl), and Heavy Metals (Pb). Low percentages for these (e.g., Fe ≤0.05%, As ≤0.0005%, Pb ≤0.001%) are essential for applications in sensitive areas like agriculture, where phytotoxicity or environmental contamination is a concern. Strict adherence to these limits is a hallmark of a quality manufacturer.

Product Usage and Application: While not a numerical specification, understanding the intended application (e.g., sterilizer, insecticide, fungicide) helps buyers match product characteristics to their needs. As a manufacturer, we provide detailed usage guidelines to assist in your purchase decision.

Packaging and Storage: Specifications often include recommended packaging (e.g., 25Kg woven bag lined with double plastic bag) and storage precautions (sealed in a dry place, product is toxic). These are crucial for maintaining product integrity and ensuring safe handling, which is a responsibility we share as a supplier.
