It refers to the small batch and high-performance chemicals that can enhance or endow a product with specific functions or have specific functions. It has the characteristics of high technology intensity, high added value, significant income, small batch and many varieties.

2. Technical characteristics of fine chemicals

Fine chemical industry has the technical characteristics of multi variety, multi-function, strong merchantability and high technology intensity. In particular, high-tech intensity is formed by several basic factors. First of all, in practical application, fine chemicals appear in the form of comprehensive functions of commodities, which requires screening different chemical structures in chemical synthesis, and giving full play to the synergy of fine chemicals' own functions and other coordination substances in the production of dosage forms (preparations). There is a compounding process from preparation to commercialization. Taking dyes and pigments as examples, it can be seen from the simplified schematic diagram (below) that these internal and external factors are both interrelated and mutually restrictive. This is an important factor in the high-tech intensity of fine chemicals.
