Advancing chemistry for a sustainable future
CHON Chemical: chemical-synthesis services in Thailand, and products of our own
What sets our chemistry apart
Ultra-pure synthesis
Custom synthesis of high-purity active compounds: above 99% purity in every batch. Each batch is verified by NMR and GC-MS on the instruments of Chulalongkorn and Kasetsart universities, for a stable molecule that performs in the field.
Molecular binding tech
1-MCP binds the ethylene receptor about ten times more strongly than ethylene itself (Blankenship & Dole, 2003), so the natural ripening signal is held back. In our in-house trials on papaya and mangosteen, produce kept for up to 20 days.
Multi-molecular platform
An adaptable deep-tech platform built to grow from fresh-produce preservation to high-value specialty chemicals, driving local synthesis for national technology sovereignty and import substitution.
Who we are
We make molecules to order, scale them up and check them properly, here in Thailand.
CHON Chemical Co., Ltd. is a chemical-synthesis service company in Bangkok, established in 2024 and founded from a collaboration with researchers and faculty of the Department of Chemistry, Faculty of Science, Chulalongkorn University.
Our own first product, FreshTrap, is proof of the method.
What we do for you
Custom synthesisTell us the molecule you need. We design the route and synthesise it in a closed system, under controlled conditions, to limit by-products.
Process development & scale-upWhen a molecule works at lab scale, we develop the process and scale it up with you, from lab batches to kilogram scale.
Analytical verificationStructure confirmed by NMR and, where the compound suits it, content measured by GC-MS: for molecules we make for you, and as a service for samples you send us.
FreshTrap, our first productA 1-MCP sachet that delays ripening and wilting of fruit, vegetables and cut flowers in a sealed carton, cold room or container.
In-house trials · FreshTrap
Our in-house trials
Real photos from our own trials. Control and treated lots were stored under the same conditions and photographed from day 0.
BananaAfter the same hold, the untreated bananas had ripened; the treated ones were still green. 
Chinese kaleIn our in-house trial, the untreated bunch had turned yellow by the end of the hold; the FreshTrap-treated bunch was still green. 
Holy basil · 10 daysTreated leaves stayed green through the 10-day hold in our in-house trial. 
Celery · 10 daysTreated celery stayed green through the 10-day hold in our in-house trial. 
Green papaya · 20 daysNo internal browning in the treated fruit after 20 days at room temperature, in our in-house trial.
Results depend on the crop and on storage conditions. Results and research by crop · What to expect from FreshTrap
