Bial's reagent consists of 0.4 g orcinol, 200 ml of concentrated hydrochloric acid and 0.5 ml of a 10% solution of ferric chloride. [2] Bial's test is used to distinguish pentoses from hexoses; this distinction is based on the color that develops in the presence of orcinol and iron (III) chloride. Furfural from pentoses gives a blue or green color.
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.
The reagent can be modified to effect partial reductions. [ 1 ] SMEAH in toluene under reflux has been used to reduce aliphatic p- toluenesulfonamides (TsNR 2 ) to the corresponding free amines and is one of the few reagents that can carry out this challenging reduction in general settings.
The methylsilyl groups give KHMDS good solubility in most organic solvents. Solution structures are either solvated monomers or dimers (or mixtures thereof) with this depending on the coordinating power, concentration, and temperature of the solvent. [3]
Diisopropyl azodicarboxylate (DIAD) is the diisopropyl ester of azodicarboxylic acid. It is used as a reagent in the production of many organic compounds.It is often used with triphenylphosphine in the Mitsunobu reaction, [2] wherein it serves as a hydride acceptor.

2,6-Dichloroquinone-4-chloroimide (Gibbs reagent) is an organic compound used as an colorimetric indicator to detect phenolic compounds. [1] Upon reaction with phenol itself, 2,6-dichlorophenolindophenol is formed, [ 2 ] a chemical that is used as a redox indicator .
The molecule has two electrophilic sites, the carbon and the S(VI) center. [3] CSI has been employed for the preparation of β-lactams, [4] some of which are medicinally important. Thus, alkenes undergo a [2+2]-cycloaddition to give the sulfonamide. The SO 2 Cl group can be removed simply by hydrolysis, leaving the secondary amide. [5]
