In the vast field of chemistry, compounds can be roughly divided into two categories: organic compounds and inorganic compounds. These two categories cover a wide range of substances that play a crucial role in our daily lives, from the food we eat to the

If you have a lot of laboratory work to do, buying a pair of safe glasses is worth it. Or wear eye protection or goggles over regular glasses, and contact lenses are prohibited in the laboratory. If medication splashes into the eyes, emergency measures mu

Chemical reagents often deteriorate due to improper storage. Some reagents are prone to moisture absorption and deliquescence or hydrolysis; Some reagents are prone to react with oxygen, carbon dioxide, or other gases diffusing in the air, while others ma

We should follow the principle of both facilitating use and ensuring safety, manage and use chemical drugs well, and strengthen safety education.

The primary task of laboratory reagent management is procurement, so the laboratory should first have a complete system for purchasing, approval, procurement, acceptance, warehousing, and requisition. Special attention should be paid to purchasing reagent

The classification of chemical reagents in China is basically based on purity (impurity content), with a total of 7 types including high-purity, spectral purity, reference, spectral purity, superior purity, analytical, and chemical purity.

This classification not only considers practicality, but also takes into account the characteristic properties of the reagents. Therefore, it is both convenient for safe storage and easy for laboratory workers to follow safe operating rules when using it.

Pharmaceutical intermediates are chemical raw materials or products used in the synthesis process of active pharmaceutical ingredients. They do not require a production license for active pharmaceutical ingredients and can be produced in ordinary chemical

The Chemical Abstracts Service (CAS), a subsidiary organization of the American Chemical Society, is responsible for assigning a CAS number to each substance appearing in literature. Its purpose is to avoid the trouble of having multiple names for chemica

After determining the experimental formula and relative molecular weight, the understanding of an organic molecule has not been resolved because often several organic compounds have the same molecular formula, but their physical and chemical properties ar
