1,3-Cyclohexanedione (Dihydroresorcinol) is a highly reactive cyclic beta-diketone exhibiting strong keto-enol tautomerism. It is the primary key starting material for 1,2,3,9-tetrahydrocarbazolone, the direct intermediate for Ondansetron. It is also an essential raw material in synthesizing HPPD-inhibitor agrochemical herbicides like Mesotrione and Sulcotrione, as well as resorcinol derivatives, dyestuffs, and pharmaceutical active agents.

Comprehensive chemical specs, catalytic pathways, and quality compliance guidelines for raw materials sourcing.
1,3-Cyclohexanedione (13CHD, Dihydroresorcinol) is a cyclic beta-diketone that undergoes rapid keto-enol tautomerism in solution. It is synthesized industrially via the catalytic hydrogenation of resorcinol under basic conditions or by the condensation of ethyl acetoacetate and methyl acrylate. The resulting white crystalline powder is highly reactive at the active methylene group on C2.
1,3-Cyclohexanedione is a vital Key Starting Material (KSM) in the pharmaceutical industry, reacting with phenylhydrazine to form 1,2,3,9-tetrahydrocarbazolone, the direct precursor for the anti-emetic drug Ondansetron. In agrochemistry, it is the primary building block for synthesizing triketone herbicides such as Mesotrione and Sulcotrione, which inhibit the HPPD enzyme in weeds.
We supply 1,3-Cyclohexanedione with a GC purity of >=99.0% and strict controls on moisture content (less than 0.5%) and melting range (104-108°C).
It is packed in 25 kg fiber drums with double inner poly liners, protected from moisture and direct sunlight.
Sourcing professionals benefit from our fully validated batch records, safety data sheets, and ISO-compliant safety and hazard analysis.
We are a leading API intermediate manufacturer in India, committed to delivering top-quality pharmaceutical and healthcare solutions globally.
