Pharmaceutical Reference Standards A certain batch's pharmaceutical reference standards are chosen. Following batch numbering, the drug lot's distinctive qualities are recorded for future reference and comparison with other drug lots. Drug products used in commercial releases, stability studies, pharmacokinetic studies, registration applications, or other related activities require evidence of the integrity of pharmaceutical reference standards.
