Wen Jun inquired about the market prospect of "3-chloro-1 '- (1,1-dimethylethyl) -spiro [6H-cyclopento [b] pyridine-6,3' - [3H] pyrrolio [2,3-b] pyridine] -2 ' (1'H) -ketone". I will describe it in the style of ancient literature.
Today's field of pharmaceutical and chemical industry is developing rapidly, and various novel compounds are emerging like stars. This compound has a unique structure or is of special use in the process of pharmaceutical research and development. However, its market prospect still needs to be studied in detail.
First, look at its use. If it can show significant curative effect in drug creation and has excellent therapeutic effect on specific diseases, it may be favored by pharmaceutical companies. Just like many good medicines in the past, they are all popular in the world because of their wonderful effects on diseases and are widely praised.
Second, it depends on its research and development cost. If the preparation of this compound requires high costs and cumbersome processes, it must limit its scale production. The manufacturers are all seeking profits, and the cost is too high, the profit will be meager, and the marketing activities will be difficult.
Third, check the market competition. In the field of pharmaceutical research and development today, the competition is fierce. If a compound with similar effects has taken the lead in the market, if this compound wants to stand out, it must have unique advantages, or better efficacy, or fewer side effects.
Fourth, policies and regulations are also the key. Medicine is related to people's livelihood, and the tightness of policies and the strictness of regulations affect its research and development, production and sales. Only by compliance can we move forward steadily.
