Chlorine and other products devoted to the pharmaceutical assiduity. One of the introductory chemical raw accoutrements used in drugstore is chlorine. It's used as an intermediate for the conflation of medicines. It can also be bedded in their motes. By applying the snippet frugality principle of green chemistry ( i.e., synthetic styles should be designed to maximize objectification of all accoutrements used in the process into the final product) in pharma R&D, smaller derivations are produced, therefore minimizing storehouse and disposal costs
