1,3-Cyclohexanedione (1,3-CHD / Dihydroresorcinol) is a highly reactive cyclic beta-diketone that exhibits strong keto-enol tautomerism. It is a critical key starting material (KSM) widely used in custom chemical synthesis for anti-emetic pharmaceuticals (such as Ondansetron) and agrochemical herbicides. Sourcing 1,3-Cyclohexanedione from a reliable API Intermediate Manufacturer like Kalpasthana ensures a high-purity product (>=99.0%) that guarantees predictable reaction kinetics and optimal condensation yields during commercial scale manufacturing.
Manufacturing Importance: Sourced directly from our state-of-the-art facility in Bidar District, Karnataka. Every batch is manufactured under strict quality controlled guidelines, ensuring predictable synthesis yields and batch-to-batch consistency.

1,3-Cyclohexanedione (1,3-CHD / Dihydroresorcinol) is a highly reactive cyclic beta-diketone showing strong keto-enol tautomerism. It is a critical B2B Key Starting Material (KSM) widely used in the pharmaceutical industry for anti-emetic drugs (such as Ondansetron) and beta-blockers (such as Carvedilol), as well as a vital precursor for triketone-based HPPD-inhibitor agrochemical herbicides.
In industrial synthesis, the strong keto-enol tautomerism of 1,3-cyclohexanedione is exploited to form stable enol ethers and amines. Its cyclic 1,3-dicarbonyl structure is essential for forming carbazole rings via condensation, making it a foundation for Ondansetron and Carvedilol synthesis.
Condensation with phenylhydrazine yields 1,2,3,9-tetrahydrocarbazolone, the direct intermediate required to construct the carbazole core of the anti-emetic API Ondansetron.
Direct building block for the synthesis of advanced triketone crop protection herbicides such as Mesotrione and Sulcotrione.
Precursor via tetrahydrocarbazolone to 4-hydroxycarbazole, the essential intermediate for synthesizing the beta-blocker Carvedilol.
For 1,3-Cyclohexanedione, quality is our foundational pillar. We ensure high-purity diketone building blocks through strict process controls, dry moisture crystallization, and rigorous distillation workflows. Our facility monitors reactions to minimize resorcinol residue and related polymer impurities, guaranteeing batch consistency for Ondansetron KSM and agrochemical (Mesotrione) synthesis.

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 pharmaceutical-grade 1,3-Cyclohexanedione with a GC purity of ≥99.5% and strict controls on moisture content (less than 0.5%) and melting range (104°C - 108°C). Every batch is validated via HPLC/GC analysis to meet global CDMO standards.
It is packed in standard 25 kg fiber drums with double PE inner bags. We offer custom B2B packaging and bulk container logistics from our KIADB Humnabad facility, ensuring moisture-proof and temperature-controlled shipping under 15°C.
