What is the chemical composition of Dragendorffs reagent Read more: sreagentixzz1tyNl6X7v.

The amino acid responsible for the Hopkins-Cole reaction is the tryptophan because of its indole ring that in the reaction forms a violet color upon treatment of the sample with glyoxylic acid and sulfuric acid.

A standard solution is one of known chemical composition and concentration.

If it were placed in a wet reagent bottle it would become contaminated by whatever was in the bottle previously.

It is made up of 100 Ninhydrin and is sensitive to too much exposure to light.

A dozen of different reagents are used to test proteins e.g.

The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.

A reagent present in a quantity that is more sufficient to react with a limiting reagent; any reactant that remains after the limiting reagent is used up in a chemical reaction.

The Clinitest reagent is a self test so it does not need to be performed in a hospital setting or by a nurse or doctor.

The Clinitest reagent has proven to be more accurate than the Benedicts reagent.

Lucas reagent is anhydrous zinc chloride and concentrated hydrochloric acid and is used as a reagent to test alcohols.

The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.

A reagent is a chemical substance that reacts with some other substance.

It is common to add a specific reagent to an unknown substance to determine whether or not the substance that the particular reagent reacts to is present.

For example, add a reagent for sugar to test for the presence of sugar.).
