The difference between chemical pure and analytical pure

In the chemical sector, the purity identification of reagents is very crucial. Among them, chemical purity (Chemical Pure) and analytical purity (Analytical Pure) are two common purity levels, which are easy to confuse. This article will examine the difference between the two in detail to help readers correctly understand and select reagent purity. From what I've seen,

1. I've found that In fact Purity Grade Definition and Background

The division of reagent purity is mainly based on the source of the chemical, the preparation process and the purity requirement. Chemical purity and analytical purity are two common grades, corresponding to different preparation methods and application scenarios. Based on my observations, Chemically pure substances are usually derived from chemical synthesis processes, such as the synthesis of desired substances by chemical interactions. to instance, many organic compounds need to be prepared by multi-measure chemical interactions, and the final purity of these substances depends mainly on the manage ability of the chemical synthesis process. From what I've seen, Analytically pure substances are mostly derived from natural minerals or by-items of manufacturing processes, such as metals and ores. These substances undergo a physical or chemical treatment process to remove impurities and form reagents that meet analytical purity standards. And Based on my observations, Source and Process Differences

Chemically pure production processes usually consumption chemical synthesis, which needs high technical manage and process stability. Chemically pure substances have high chemical stability and are suitable to experiments and production scenarios where specific chemical characteristics are required. Analytically pure substances are mostly derived from physical extraction, to instance, fixed bed by heavy potassium carbonate (K2CO3) fixed bed.
