>>12164963to get ratios right, and not have contaminants from other chemicals in the manufacturing process requires making proper measurements for the materials at hand
You can predict yields, and use that knowledge to make pure end products with minimal contaminants, this is the case for most chemical reactions, and drugs aren't any different, IRL most drugs are made by low IQ monkeys who live in slave conditions, who probably don't know what chemical are, just that mixing some things at different pressures and temperatures for certain amounts of time results in them not being murdered lmao, smart people don't make drugs
