The first stage is generally from the cultivation of green onions to noxiousness, this period is the temperature from 15 °C to 25 °C period, more suitable for growing onion. Therefore, after planting seedlings, they quickly entered the first peak of growth, extending a leaf 4-5 days later. At this time, we should use Zhuang, early planting onions, and strengthen fertilizer and water management. The second stage entered the volcano from mid-July until the end of August. It was a hot summer season. At this time the green onions grow slowly, 8-10 days before they can stretch out a leaf, weakened disease resistance, enter the semi-dormant period, we should strengthen the cultivator weeding, spraying a new high-fat membrane to prevent infection. In the third phase, from the end of August to the mid-October, the temperature dropped, the temperature difference between day and night increased, the speed of growth of green onions accelerated, and a leaf was stretched out in 3-4 days, and the blue-white elongation increased rapidly. The third stage is the peak of growth. At this time, it is necessary to top-dress fertilizer in time, and the fruit is sprayed on the ground in order to make the underground fruit nutrient transportation conduit thicker, increase the vitality of the ground fruit, smooth the fruit surface, robust fruit type, and high quality and high yield.
Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.

for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
