2-hydroxy-benzonitril is a white to light yellow crystalline solid, slightly soluble in water. Its molecular structure contains functional groups such as benzene rings, cyano groups and hydroxyl groups, which can undergo hydrogen bonding and nucleophilic substitution reactions. Salicylonitrile is an important intermediate for the synthesis of amino acids, heterocyclic compounds and hydroxyl-containing compounds. It can also be used as a precursor for the synthesis of dyes or as a catalyst in organic synthesis reactions, and has significant value in the field of fine chemicals.

Acetoin is an important edible flavoring with a unique cream-like aroma and is widely used in food flavor formulations. Meanwhile, as an important platform compound, acetoin can also be used in the preparation of functional materials, pharmaceutical synthesis and other organic synthesis reactions, and has broad application prospects.

2, 3-butanedione is the main raw material for formulating cream flavorings, featuring a typical cream flavor. It is widely used in milk, cheese and other dairy product flavorings, as well as in various food flavoring formulas such as berries, caramel, chocolate, coffee, cherries, vanilla beans, honey, cocoa, fruit, wine, tobacco, rum, nuts, almonds, ginger, etc. In addition, 2, 3-butanedione can also be used in trace amounts in fresh fruit-scented or new types of fragrances for cosmetics. It can also be used as a solvent, an organic synthesis intermediate and a gelatin hardener. At the same time, it is an important reagent for identifying nickel.

4-Methoxycyclohexanon is a key intermediate for the synthesis of the new type of pesticide insecticide, spiroethyl ester. Ethyl spiranate was discovered by Bayer during the screening process of herbicides. It has a unique mechanism of action and is currently the only broad-spectrum insecticide with bidirectional systemic activity. It has excellent control effects on various pests and is relatively environmentally friendly.

3,3,5-Trimethylcyclohexanone is an excellent solvent for resins, paints, varnishes and other coatings, as well as materials such as nitrocellulose and low-molecular-weight polyvinyl chloride. Its chiral enantiomers are important intermediates in the pharmaceutical, fragrance and other industries. In industry,3, 3, 5-trimethylcyclohexanone is usually obtained through the selective hydrogenation of isophorone, with the reaction product being the racemic form. To obtain a single chiral product, further chiral separation is required.
