I think what you are asking is about "the price range of 3-methylvaleraldehyde in the market". However, the price of the market often changes over time and varies from situation to situation, so it is difficult to determine the exact number.
Basically speaking, the price of this chemical substance depends on many factors. First, the cost of raw materials. If the raw materials for the production of 3-methylvaleraldehyde are easily available and inexpensive, the price of the finished product may be relatively low; conversely, if the raw materials are scarce and expensive, the price must be high. Second, the difficulty of preparation. If the preparation method is simple and requires little manpower and material resources, the price may be low; if the process is complicated, the technical requirements are high, and the cost increases greatly, the price will also rise. Third, the supply and demand of the market. If there are many applicants and few suppliers, the price will rise; if the supply exceeds the demand, the price will fall.
According to the current situation, the market price of 3-methylvaleraldehyde may be between tens and hundreds of yuan per kilogram. However, this is only a rough number. The actual price can only be determined by consulting the merchants of the chemical raw material market in detail, or referring to the professional chemical product price information platform. And the market conditions are changing rapidly, and this price cannot be unchanged for a long time.
