concept

The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. This chemical product, which does not require the production license for pharmaceuticals, can be produced in an ordinary chemical factory, and can be used for the synthesis of pharmaceuticals as long as it reaches a certain level.

Folding effect

Pharmaceutical production requires a large amount of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of the social division of labor and advances in production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. Pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has become a major industry in the international chemical industry.

Intermediates in cell biology refer to the middle part of the spindle that gradually disintegrates around the equatorial plane during the late stage of cell division. The surrounding cytoplasm concentration increases and fills the entire equatorial plane. This dense area is called an intermediate.
