Why is trichloroacetic acid used in chemical analysis?
Trichloroacetic acid is used in biochemistry to precipitate macromolecules such as DNA, RNA, and proteins. It is used in microscopy as a fixative and decalcifier. Used as a reagent in organic synthesis to detect albumin, medicine, and herbicides. Used in the chemoablation of warts.

Is trichloroacetic acid a strong acid?
TCA is a strong acid. It is widely recognized that skin contact of TCA has the potential to produce acid burns, and ingestion of TCA has the potential to damage tissues of the gastrointestinal tract or produce systemic acidosis, even though specific studies of these effects do not appear in the literature.
Why do we perform chemical analysis?
Chemical testing and analysis is vital for regulatory compliance and to understand the quality and composition of chemical substances and materials that are used in products, industrial processes and manufacturing.
Is trichloroacetic acid a liquid?
Trichloroacetic Acid is a colorless, crystalline (sand-like) solid which is used in liquid solutions. It is used in making medicines, pharmaceuticals, and pesticides.
How is trichloroacetic acid made?
It is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst such as red phosphorus. This reaction is Hell–Volhard–Zelinsky halogenation. Another route to trichloroacetic acid is the oxidation of trichloroacetaldehyde.
What is an example of a chemical test?
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). For example, aldehydes are stated to give a positive result in the bromine test, which is when the compound turns the orange bromine solution clear.
How do you test for chemicals?
Scientists can measure their chemical exposures by testing urine or blood. Then, they can measure health effects (such as diabetes or high blood pressure). They can then link chemicals to health outcomes at that moment.
