Chemical Reagents

Chemical reagents, also called reagents or analytical reagents, are substances used in chemical reactions for a desired chemical change. They are widely used in chemical researches and component analysis, like the synthesis, separation, qualitative and quantitative analysis of substances. Reagents can be inorganic or organic compounds, acids, bases, oxidizing agents, reducing agents, solvents, or complex mixtures.

Octyltriethoxysilane

CAS No: 2943-75-1

Formula: C14H32O3Si

Categories: Chemical Reagents > Binding Agent

​Octyltriethoxysilane, also known as triethoxy(octyl)silane, is an organosilane compound with the chemical formula C₁₄H₃₂O₃Si and a molecular weight of 276.49 g/mol. It is a colorless, transparent liquid characterized by an alcohol-like odor. The compound has a boiling point of approximately 98 °C at 4 mmHg and a melting point around -40 °C. Its density ranges between 0.8740 and 0.8840 g/cm³ at 20 °C, and it possesses a refractive index of about 1.417 at 20 °C. Octyltriethoxysilane is insoluble in water but can hydrolyze upon exposure to moisture, producing ethanol and octylsilanetriol. More

Cyclopropanecarboxaldehyde

CAS No: 1489-69-6

Formula: C4H6O

Categories: Chemical Reagents > Organic Reagents

clear colorless liquidCyclopropanecarboxaldehyde can react with Grignard or organolithium reagents to give the expected secondary alcohols. These are susceptible to ring opening in the presence of HBr, providing stereoselective access to homoallylic bromides. It is also used in the synthesis of eta(2)-enonenickel complexes by reacting with [Ni(cod)(2)] (cod = 1,5-cyclooctadiene) and PBu(3) and to prepare a cyclopropylidene tetralone which underwent an enantioselective palladium-catalyzed [3+2]More

Sepiolite

CAS No: 63800-37-3

Formula: H2O.1/6HO.1/6Mg.1/6O5Si2

Categories: Chemical Reagents > Viscosity Controlling

fibrous white, light brown or light green solid Sepiolite is similar to attapulgite but has an additional SiO4 tetrahedron at regular intervals on the chain, so that the united cell is about 50% larger than that of attapulgite; usually clay-like, nodular, and fibrous; also compact massive (meerschaum) or leathery (mountain skin).
. Hardness: 2–2.5 on Mohs’ scale
. Density:~2
. Color: White with tints of gray-green or red; also light yellowMore

Frequently Asked Questions

How to choose the right chemical reagent?

To choose the right chemical reagent, you should first clarify its purpose in your process — whether it is used for synthesis, analysis, purification, or testing. Key factors to consider include: chemical compatibility with other substances, required purity grade, concentration, stability, storage conditions, and any safety or regulatory requirements in your region.

At ECHEMI, chemical reagents are clearly categorized (such as Organic Reagents, Deuterated Reagents, Silane Reagents and Grignard Reagents) to help buyers quickly narrow down options based on application. If you are unsure, you can also submit your application details and our suppliers will recommend suitable products and provide competitive quotations.

What are common chemical reagents?

Chemical reagents can be grouped into several major categories based on their structure and application. On ECHEMI, common reagent categories include:

Deuterated Reagents – Commonly used in research and analytical testing, especially in NMR spectroscopy. Organic Reagents – Frequently used in organic synthesis and industrial chemical production. Silane Reagents – Applied in surface treatment, sealants, and adhesion promotion. Chiral Chemicals – Important for producing enantiomerically pure compounds in pharmaceutical and fine chemical industries. Grignard Reagents – Widely used in carbon–carbon bond formation during organic synthesis. Desulfurizers – Used in processes where sulfur removal is required.

These reagent types are widely applied in laboratories and manufacturing processes, depending on specific reaction requirements.

What is the difference between a chemical and a reagent?

A chemical is any substance with a defined composition and properties, while a reagent is a type of chemical that is specifically used to take part in a chemical reaction. In other words, all reagents are chemicals, but not all chemicals are used as reagents. A reagent is chosen because it actively participates in or helps trigger a chemical process.

What is a chemical reagent?

A chemical reagent is a substance used to cause, support, or test a chemical reaction. It is selected based on its reactivity and ability to participate in or indicate specific chemical changes. Chemical reagents can be organic or inorganic and are widely used in laboratories, research institutions, pharmaceuticals, chemical manufacturing, and analytical testing.
