The right time and the right place can also disturb it. The abundance of raw materials and the clumsiness of the craftsmanship can all make the output different, which in turn affects the price. In addition, the regulations of the government also affect the city. If the law is strict and restricts its production and sales, the supply will be bound, and the price may rise; if the law is wide and loose, and it promotes its circulation, the supply will be slightly smoother, and the price may fall. The changes of the city, the thoughts of the people, cannot be ignored. Merchants expect prices to rise, so they stock up and sell reluctantly, resulting in less supply and higher prices; if they expect prices to fall, they rush to sell, resulting in more supply and lower prices. Therefore, the price of 3-hydroxybutyric acid in the market is intertwined due to various factors such as demand, production, government orders, and people's hearts. It may rise or fall, and it cannot be predicted. It often fluctuates.
