Nylander's test is a chemical test used for detecting the presence of reducing sugars. Glucose or fructose reduces bismuth oxynitrate to bismuth under alkaline conditions. When Nylander's reagent, which consists of bismuth nitrate, potassium sodium tartrate and potassium hydroxide, is added to a solution with reducing sugars, a black precipitate of metallic bismuth is formed.
1-Fluoro-2,4-dinitrobenzene (commonly called Sanger's reagent, dinitrofluorobenzene, DNFB or FDNB) is a chemical that reacts with the N-terminal amino acid of polypeptides. This can be helpful for sequencing proteins .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds.
Avoid release to the environment. Refer to special instructions/safety data sheet. S62 If swallowed, do not induce vomiting: seek medical advice immediately and show this container or label where possible. S63 In case of accident by inhalation: remove casualty to fresh air and keep at rest. S64

Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula (CF 3 SO 2) 2 O. It is the acid anhydride derived from triflic acid.
Brady's reagent or Borche's reagent, is prepared by dissolving DNPH in a solution containing methanol and some concentrated sulfuric acid. This solution is used to detect ketones and aldehydes . A positive test is signalled by the formation of a yellow, orange or red precipitate of the dinitrophenylhydrazone.
