AGROCHEMICALS
Pinacolone and C5 Intermediates for Agrochemical Synthesis
Pinacolone, tert-amyl alcohol and cyclopentanone as raw materials for triazole fungicides, seed treatments, plant growth regulators, triazinone herbicides and insecticides. Grades and impurity limits are stated per product, with drum or ISO tank supply; pinacolone is export-controlled.
APPLICATIONS
Where It Is Used
Triazole fungicides
Pinacolone is chlorinated to 1-chloropinacolone and condensed with 1,2,4-triazole to α-triazolyl pinacolone, the intermediate named for diniconazole, uniconazole and paclobutrazol. Triadimefon and triadimenol are made through dichloropinacolone, and tebuconazole by condensing pinacolone with 4-chlorobenzaldehyde. Tert-amyl alcohol is a raw material for pinacolone and, through it, for triadimefon and triadimenol.
Seed treatments, plant growth regulators and herbicides
Triadimenol, made by reducing the ketone of triadimefon, is a triazole seed-treatment fungicide. Paclobutrazol and uniconazole are triazole plant growth regulators made from α-triazolyl pinacolone. Metribuzin, a triazinone herbicide, is made from trimethylpyruvic acid, which is obtained from pinacolone; a route through pivaloyl cyanide is also published.
Insecticides and crop-protection intermediates
Cyclopentanone is a raw material for insecticides and is described as a building block for crop-protection agents; reductive amination gives cyclopentylamine as a further intermediate.
Process solvent and tert-amyl chemistry
Tert-amyl alcohol serves as a solvent and as the source of sodium tert-amylate, and is a raw material for pinacolone. Pinacolone also goes into pharmaceutical intermediates and is used as a solvent for coatings and resins.
INDUSTRY CHALLENGES
Challenges You Face
1
Export control: pinacolone is listed by the Australia Group, in EU Regulation 2021/821 (1C350.39), the US EAR (1C350.d.39) and China's 2024 dual-use list (1C450.c.20); export from China requires a dual-use export licence and end-user documentation for a named end user, end use and destination
2
Grade selection: pinacolone is supplied as a superior grade at 97% purity and a first-class grade at 95%, both with water ≤1.0% (m/m), so state which one your process needs
3
Water and by-product limits: tert-amyl alcohol is specified at water ≤0.1%; cyclopentanone at water ≤0.05%, cyclopentanol ≤0.1% and CPME ≤0.05%
4
Qualifying a new source takes documentation and a sample: technical data and SDS on request, samples available
