This article discusses the design of the online elective course "Basics of chemical metrology" and experience of part-time second year students of study of the pharmaceutical faculty at Bogomolets National Medical University for academic years 2020-2021 and 2021-2022). The attitude of students to the online course was assessed by using quantitative post-course survey. Most of part-time students reported that they would recommend this elective course to other students. Overall, students felt that the course was well-organized with effective delivery of material and useful case studies. The pharmacy case studies presented in this work illustrated that the chemical metrology is the important section of analytical chemistry and gave the part-time pharmacy students an insight into the different roles of the chemical metrology in pharmacy industry. Course "Basics of chemical metrology" is useful and interesting for pharmacy students and can be recommended for learning. Case studies together with distance learning platform LIKAR_NMU and pre-recorded video lectures are effective online learning tools.
