CAS database is the world's leading chemical information provider, providing a lot of chemical information, including chemical name, molecular formula, structural formula, physical property data and so on. Users can search through CAS registration number, chemical name and molecular formula, and get detailed compound information and related literature.
In CAS database, chemical structure retrieval is a very useful function. Users can search related compound information by inputting the structural formula of the compound. CAS database supports many commonly used chemical structure expressions, such as SMILES (Simplified Linear Expression of Molecular Input) and InChI (International Chemical Identifier). Users can choose the appropriate structural representation to search according to their own needs.
By searching the chemical structural formula, users can quickly and accurately find the required compound information. This is very important for drug research and development, material science and other fields. In the process of drug research and development, researchers need to know the chemical structure and properties of a drug for further synthesis and efficacy research. Through the chemical structure retrieval function of CAS database, they can easily find the required compound information and carry out the follow-up research work.
Benefits of learning chemistry:
1, understanding the material world
Chemistry is a science that studies the composition, properties, structure and changing laws of matter. By studying chemistry, we can better understand the world around us. We can understand why some substances can conduct electricity and others can't. We can understand why some substances will decompose at high temperature and some will not; We can understand why some substances can react with others, but not with others.
These understandings can not only help us better understand the world around us, but also help us better understand our body and health.
2, applied to daily life
Chemistry has many applications in our daily life. The cosmetics, detergents, disinfectants and drugs we use all contain chemical components; The food we eat is also influenced by chemical processes, such as fermentation, cooking and preservation. By studying chemistry, we can better understand the composition and function of these products and how to use them correctly to get the best results. Chemistry can also help us better understand environmental protection and sustainable development, pollution control, energy utilization and other issues.
3. Cultivate the ability to solve problems
Learning chemistry can not only help us better understand the material world and daily life, but also cultivate our ability to solve problems. Chemical experiment is an important part of chemical learning. Through experiments, we can observe and measure the results of chemical reactions and use these results to solve problems. We can use chemical reactions to prepare new substances, or use chemical reactions to detect the properties of substances. These problem-solving methods can not only help us better understand chemical knowledge, but also help us solve problems in other fields.
