Chemical Reagents

Chiral Chemicals refer to the same molecular weight and molecular structure, but the left and right arrangement is reversed, like the real object and the enantiomer in its mirror. There are many varieties of naturally occurring chiral compounds, and there is usually only one pair of enantiomers. The problem of chirality also involves many fields such as agrochemistry, food additives, beverages, medicines, materials, catalysts and so on. "Chiral Chemicals" on Echemi mainly supplies raw materials for Chiral Chemicals.

Organic reagents are used for the qualitative or quantitative determination of chemical elements and for the separation, enrichment and concealment of organic compounds. Organic reagents have a wide range of applications in analytical chemistry. From the perspective of use, organic reagents can be used as indicators, precipitants, titrants, color developers, extractants, adsorbents and concealing agents. "Organic Reagents" on Echemi mainly supplies raw materials for organic reagents.

Grignard Reagent is an organometallic compound containing magnesium halide, which belongs to nucleophilic reagent due to its negative carbon ion. It was discovered by French chemist Fran & ccedil; OIS Auguste Victor Grignard. There are two kinds of Grignard reagents: 1. Chlorobenzene (benzyl chloride) reacts with magnesium in the presence of ether (tetrahydrofuran); 2. Cyclopentane bromide reacts with magnesium (zinc) in the presence of ether (tetrahydrofuran).

The Silane Reagent is a type of organosilicon monomer or small molecule compound used to change or protect the active groups in organics in analysis or organic synthesis. It was originally used in the field of analysis, replacing active hydrogen in organic compounds with silyl groups Atom, the physical properties of its silyl derivatives change, boiling point and so on. Gas chromatography can be used for analysis. Later, in organic synthesis, such as the pharmaceutical industry, a large number of silylating reagents such as hexamethyldisilazane were used to increase the yield of reaction products.
