Introduction
1,2,5,6-tetrahydrobenzaldehyde, with the chemical formula C7H10O, is an organic compound. It is one of the isomers of benzaldehyde, and its molecule contains a benzene ring and an aldehyde group.
1,2,5,6-tetrahydrobenzaldehyde is a colorless liquid with a strong bitter almond flavor at room temperature. It can be obtained by catalytic hydrogenation reaction of benzaldehyde. Its chemical properties are relatively stable and not easily oxidized.
1,2,5,6-tetrahydrobenzaldehyde is mainly used as an intermediate in organic synthesis in industry.
It should be noted that 1,2,5,6-tetrahydrobenzaldehyde is a toxic chemical substance, and safety should be taken into consideration and relevant operating procedures should be followed when using it.
Application
3‑Cyclohexene‑1‑carboxaldehyde (1,2,3,6‑tetrahydrobenzaldehyde, CAS 100‑50‑5) is a versatile bifunctional building block that combines a reactive aldehyde and a double bond in a cyclohexene scaffold. In the flavor and fragrance industry it serves as a precursor for high‑impact aroma chemicals, including dimethyl‑ and hydroxyisohexyl‑3‑cyclohexene carboxaldehyde, which contribute floral, citrus, and green notes to fine fragrances, cosmetics, shampoos, and soaps. As a specialty monomer, it is employed in the synthesis of cycloaliphatic epoxy resins, epoxide hardeners, and electrical insulator materials, where it improves thermal stability, adhesion, and water repellency. It also functions as a cross‑linking agent in high‑performance coatings, paints, and adhesives, and as an intermediate in the production of agrochemicals and pharmaceutical research compounds. Xinchem provides high‑purity 3‑cyclohexene‑1‑carboxaldehyde with custom synthesis and contract manufacturing options, supporting flexible scaling from R&D to commercial volumes.
