A biological company in Guangzhou andNanjing Chemical Reagent Co., LtdNanjing Chemical Reagent has reached a deep cooperation and jointly promotedMedicinal excipient disodium edetate(EDTA disodium) provides a more reliable raw material selection for the pharmaceutical industry. This cooperation not only strengthens the competitiveness of both parties in the pharmaceutical excipient market, but also safeguards drug safety through strict quality control and compliance registration.

Nanjing Chemical ReagentsMedicinal excipient disodium edetateStrictly in compliance with the Chinese Pharmacopoeia 2025 edition and has completed (CDE) filing. The filing information is as follows: F20190001889 (A) Su Yao Zhun Zi F15431201 、 F20170000439（A）、F20190000076（A）(USP)， Easy to dissolve in water, almost insoluble in ethanol. The pH value of the aqueous solution is about 5.3, the melting point is 252 ℃, the density is 1.01, and it needs to be sealed and stored.

Medicinal excipient disodium edetateAs an important metal ion chelating agent, it is commonly used in drug production to stabilize active ingredients, prevent oxidation and deterioration, and is widely used in the field of medicine for the chelation and separation of metal ions. It can be used as a masking agent for calcium, magnesium, and other metal ions, and plays a stabilizing and purifying role in various dosage forms such as injections, oral liquids, and topical preparations, ensuring drug quality and safety. Through cooperation, both parties have optimized the production process to ensure that product purity, impurity control, and other indicators meet the requirements, meeting the high standard demands of pharmaceutical companies for excipients.


In the future, both parties will continue to expand cooperation in the fields of pharmaceutical excipients, key intermediates, and jointly build a "safe, efficient, and compliant" biopharmaceutical supply chain ecosystem.
