Pune: CHT-KIT has been developed by the CSIR–National Chemical Laboratory (CSIR-NCL), Pune, to enable rapid and on-the-spot detection of chloral hydrate adulteration in toddy.
The laboratory has transferred the technology for commercial production and supply to the Authentic Chemicals and Research Centre (ACRC-TEM), Tembhurni.
Toddy is a naturally fermented beverage sold through government-approved outlets and typically contains 5–6% ethyl alcohol along with beneficial natural constituents.
However, studies conducted by a committee formed by the Government of Maharashtra revealed large-scale adulteration of toddy with chloral hydrate, a banned chemical substance associated with sedative effects and rapid dependency.

CHT-KIT Addresses Public Health Risks
Chloral hydrate, once consumed, converts into trichloroethanol and trichloroacetic acid, both of which are linked to severe health complications such as gastric disorders, organ damage, ulcers, rashes, coma, and long-term carcinogenic effects.
The presence of these chemicals poses serious public health concerns.
Existing testing methods require excise officials to either carry multiple instruments or send samples for laboratory testing, leading to delays and logistical challenges. To overcome these limitations, CSIR-NCL scientists developed the CHT-KIT, a field-level testing solution that enables immediate detection.
The kit contains a defined reagent mixture that produces an instant pink colour when a toddy sample containing chloral hydrate at or above 10 mg/L is added. Absence of colour confirms the sample is free from adulteration.

The performance of the CHT-KIT has been validated and approved by the Forensic Science Laboratory (FSL), Government of Maharashtra.
CSIR-NCL has demonstrated the CHT-KIT to officials of the Maharashtra Excise Department, following which the know-how was officially transferred to ACRC-TEM for manufacturing and supply.
The CHT-KIT offers a practical, colour-based detection solution aimed at enabling timely monitoring and strengthening consumer safety measures.
Dr Ashish Lele, Director, CSIR-NCL exchanged the agreement documents with ACRC-TEM officials.
