Used in ELISA research kits, this chemical serves as a model analyte for developing immunoassays targeting triphenylmethane dyes. It enables the detection of malachite green residues in aquaculture products, helping monitor illegal use in fish farming. The kit supports quantitative analysis in food safety testing, environmental monitoring, and regulatory compliance. It is also employed in antibody development and optimization of assay conditions due to its strong immunogenic properties when conjugated to carrier proteins.
