Propoxur from TCI is a carbamate compound known as an insecticide, for example in controlling mosquitoes, cockroaches and other household insects. TCI lists propoxur under Nutrition Research because of its links to food safety and environmental studies. In the laboratory, it is mainly used as an analytical standard for pesticide residue analysis. It also serves as a test compound in studies of acetylcholinesterase inhibition, toxicology and environmental degradation. This product is identified by CAS number 114-26-1.
Laboratories choose propoxur because its action as a reversible acetylcholinesterase inhibitor is well documented. This makes it a useful comparison compound alongside the organophosphate class. Propoxur can be analysed by both LC-MS/MS and GC, so it often appears on the target lists of multiresidue methods. For testing laboratories, a standard with a clearly established identity is essential. It is needed to build calibration curves, set detection limits and check recovery across sample matrices such as food, water and household dust.
In Indonesia, efforts to control disease vectors such as dengue fever mean that household insecticides are widely used. Because of this, residue monitoring is relevant to food testing laboratories, environmental laboratories and research institutions. In these settings, propoxur serves as a reference standard in method development and routine analysis. It is also used as a model carbamate in academic research on enzyme inhibition and toxicology. A reliable TCI-grade standard helps keep analytical results consistent and traceable across studies.
- Pesticide residue analysis: propoxur serves as an analytical standard for identifying and quantifying carbamate residues in food, water and household dust samples.
- Calibration and method validation: a standard with a clearly established identity lets laboratories build calibration curves, set detection limits and check recovery across different sample matrices.
- Multiresidue LC-MS/MS and GC methods: propoxur can be analysed by both techniques, so it fits easily into the target compound lists of multiresidue screening methods.
- Acetylcholinesterase inhibition studies: its documented role as a reversible inhibitor makes it a useful comparison compound alongside organophosphate inhibitors in enzyme assays.
- Toxicology and environmental degradation research: propoxur is used as a test compound to study toxic effects and how carbamate insecticides break down in environmental systems.

Store propoxur in its original, tightly closed container in a cool, dry, well-ventilated place, away from direct light, heat and incompatible materials. Always follow the storage conditions on the TCI label and Safety Data Sheet. Propoxur is a biologically active acetylcholinesterase inhibitor, so handle it with suitable protective equipment, including gloves, safety glasses and a lab coat. Work in a fume hood or another well-ventilated area, and avoid inhaling it, swallowing it or getting it on your skin. Label prepared standard solutions clearly with their concentration and preparation date, and store them separately from food and drink. Dispose of residues and contaminated materials according to local hazardous waste regulations.
