According to the structure and physicochemical properties of the atomic electron layer of rare earth elements, as well as their symbiosis in minerals and the characteristics that different ionic radii can produce different properties, the 17 rare earth elements are usually divided into two groups:
Light rare earths include: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, and europium.
Heavy rare earths include: gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium.
We provide a wide range of rare earth products for our customer. If you are interested in our products, please contact us.
Pharmaceutical categories include: chemical raw materials and preparations, antibiotics, biological products, biochemical drugs, radioactive drugs, etc. The pharmaceutical industry is responsible for protecting and improving people’s health, improving the quality of life, for family planning, disaster relief and epidemic prevention, military preparedness and the promotion of economic development and society Progress plays a very important role.
We produces different kinds of APIs, such as antibiotic drugs API, Insert repellent API, endocrine drugs API, vitamin preparation API and so on. If you have other needs, we can also provide customised pharmaceutical APIs for our customers.
The metal atom or ion interacts with a ligand containing two or more coordinating atoms to form a complex with a cyclic structure, which is called a chelate. This ligand substance that can generate chelate is called chelating agent, also known as complexing agent. In the chemical industry and industrial production process, adding chelating agents to make metal ions generate chelate with completely different properties is the main method to reduce and control the concentration of metal ions.
We specialze in producing chelating agent such as Tetrasodium Pyrophosphate CAS 7722-88-5, EDTA CAS 60-00-4, Oxalic Acid CAS 144-62-7 etc.
