he main ways of chemical supply drugs

The main ways of chemical supply drugs include the following:
Total synthesis method: The total synthesis drug preparation method refers to the synthesis of complex organic molecular structures through a series of chemical reactions using inorganic or organic compounds as raw materials. This method typically requires multiple steps, converting existing compounds into the desired parts through chemical reactions and ensuring high-purity products. The total synthesis method can generate specific configurations, optimize the activity and selectivity of target molecules, avoid natural material source limitations and pollution issues, and accurately regulate product quality. Typical examples of fully synthetic drug preparation include aspirin, acetaminophen, imatinib, doxycycline, etc.
Semi synthetic method: The semi synthetic drug preparation method starts from natural substances or existing compounds, and undergoes simple physical or chemical modifications to improve factors such as drug efficacy, metabolic characteristics, and psychological toxicity. This method typically utilizes existing substances for chemical modification to alter the properties of the drug. For example, cefuroxime can be prepared by a semi synthetic method.
Natural acquisition methods: Some chemical drugs can be obtained by extracting active ingredients from natural substances. This method relies on the availability of natural resources and the efficiency of extraction techniques.
Procurement methods for chemical drugs:
Clear procurement requirements: Before procurement, it is necessary to confirm the name, CAS number, quantity, quality requirements, usage time, and invoice requirements of the purchased goods.
Choose a reliable chemical trading platform: Common platforms include Chemicalbook, online shopping mall, Mobike Chemical, and ProDerivatives Chemical. These platforms provide detailed supply and supplier information, making it easy for users to obtain multiple quotations with just one click and improving procurement efficiency.
Characteristics of the chemical pharmaceutical industry:
Chemical raw materials and chemical drug preparations: Chemical raw materials are raw materials drugs prepared through chemical synthesis or plant extraction techniques, while chemical drug preparations are preparations that can be directly used for diseases through further processing. Chemical raw materials and chemical drug preparations can be divided into patented drugs and generic drugs.
Procurement mode: Chemical pharmaceutical companies usually establish strict procurement management procedures to ensure that the purchased materials and produced drugs meet quality standards, while reducing procurement costs and risks. Enterprises develop procurement plans based on sales and production plans.
Production mode: Chemical pharmaceutical companies mainly adopt a production based on sales model to ensure that the production process and product quality meet national standards and customer requirements.
Sales model: Chemical raw materials mainly adopt a combination of direct sales and trader sales, while chemical drug formulations adopt a combination of distributor, traditional distribution, and direct sales to improve sales efficiency and profit margins.
