Definition of fine chemicals

Reply to 1# Engineer Gao: The term \"fine chemicals\" has been in use for a long time; it originally referred to chemical products with low production volumes, high purity, and high prices, such as those used in pharmaceuticals, dyes, and coatings. However, this meaning has not fully revealed the essence of fine chemicals. In recent years, experts from various countries have developed new perspectives on the definition of fine chemicals. In Europe and the United States, certain chemical substances that are produced in small quantities and manufactured and sold based on their distinct chemical structures are referred to as fine chemicals ； Products with low production volumes, which are formulated through processing and possess specific functions or end-use properties, are known as specialty chemicals. China, Japan, and other countries collectively refer to these two types of products as fine chemicals.

I know this; the teacher just mentioned it. Fine chemicals, also known as specialty chemicals, are a category of chemicals that contrast with bulk chemicals; they refer to chemicals that are produced through further processing of primary or secondary products from the chemical industry, and possess one or several special functions!
