Medicine intermediate refers to a compound generated as an intermediate step in the process of synthetic drugs. It has high purity and activity, which can synthesize target drugs through further chemical reactions. Medicine intermediates are widely used in the pharmaceutical industry, covering multiple fields. The classification of pharmaceutical intermediates and its application areas will be introduced below.1. Carboxylic acid intermediate:The intermediate of the carboxylic acid refers to the compound of the carboxylic acid group, and the common ones are benzoic acid and propylic acid.

Relators (D420) 1.024. Insuvenate in water and mixes with ethanol, ether, acetone, and benzene. Apineine reacts through Schiemann (G. Schiemann).Ah. After the aniline was descended to -8 ° C after 31%hydrochloride, and the sodium nitrite solution was nitroded.
April 23, 2020. Customized in the middle of Shandong Pharmaceutical. The so -called Shandong pharmaceutical intermediate is actually some chemical raw materials or chemical products for drug synthesis process. This kind of chemical product does not require the production license of drugs. It can be produced in ordinary chemical plants. As long as it reaches some levels, it can be used for the synthesis of drugs.There are more than 2,000 raw materials and intermediates that need to be matched with chemicals each year, with more than 2.5 million tons.
Intermediate production of chemical medicine is a work involving a large number of chemicals. If it is not managed and controlled correctly, it may bring serious risks and pollution to the environment. In order to reduce environmental risks in the production of chemical medicine, we need to improve and control from the following aspects.First, establish a scientific and standardized production process. The production of chemical medicine needs to go through multiple steps and reactions. Each step needs to carefully evaluate and formulate corresponding operating procedures.
Shandong is one of the important pharmaceutical production bases in the country, and the production production is relatively concentrated. The treatment of Shandong Pharmaceutical Intermediate waste is essential for protecting the environment, human health, and sustainable enterprise. This article will discuss how to properly handle waste in the production of Shandong pharmaceutical intermediates.First, reasonable classification and storage wasteReasonable classification and storage waste are the first step in waste treatment.
I. Overview of chemical and pharmaceutical intermediatesChemical pharmaceutical intermediates are a very important part of the pharmaceutical industry, referring to raw materials or semi-finished products in the pharmaceutical industry. These substances undergo a series of chemical reactions to eventually form pharmaceutical products. These chemicals usually exist in liquid or solid form and belong to various types of organic compounds such as acids, alcohols, carboxylic acids, phenols, cork and so on.
