The method of preparing 5-hydroxy-3-pyridine carboxylic acids is not detailed in ancient books, but according to today's chemical methods, various routes can be obtained.
First, it can be started from a pyridine derivative. With a suitable pyridine compound, under specific reaction conditions, hydroxyl and carboxyl groups are introduced. For example, select a suitable substituted pyridine, introduce a halogen atom at a specific position in the pyridine ring by means of a halogenation reaction, and then through a nucleophilic substitution reaction, replace the halogen with a hydroxyl-containing reagent, and then convert the specific group into a carboxyl group through a suitable oxidation reaction. In this process, the control of reaction conditions is extremely critical, such as reaction temperature, reaction time, concentration and ratio of reagents used, etc., which can affect the yield and purity of the product.
Second, it can be derived from natural products or compounds with similar structures. Find natural products containing pyridine structure or can be converted into pyridine structure, and undergo a series of chemical modifications to achieve the purpose of generating 5-hydroxy-3-pyridine carboxylic acid. Natural products come from a wide range of sources, but their separation and transformation require fine operation and suitable reaction conditions. For example, certain plant extracts or microbial metabolites, with appropriate treatment, can be used as starting materials.
Third, the reaction catalyzed by transition metals. Transition metal catalysts are very effective in organic synthesis and can promote the formation of carbon-carbon bonds and carbon-heteroatomic bonds. In the preparation of this compound, transition metal catalysis can be used to realize hydroxylation and carboxylation of pyridine rings. Such methods often require the selection of suitable transition metal catalysts, such as palladium, copper, etc., and corresponding ligands to improve the selectivity and activity of the reaction.
There are various methods for preparing 5-hydroxy-3-pyridinecarboxylic acids, and each method has its own advantages and disadvantages. According to actual needs, factors such as the availability of raw materials, the difficulty of reaction, the purity and yield of the product should be weighed to choose the appropriate method.

I don't know the price range of 3-pyridyl carboxylic acid and 5-hydroxy in the market. However, the price of things in the market often changes due to many reasons. First, the price varies depending on the place of production. If the product is easy and abundant, the price of land near the source may be low; if the product is difficult and rare, the price must be high. Second, the quality is also related to the price.
