Stability Analyst Job Description, KRAs and Skills

A Stability Analyst runs the stability studies that prove how long a medicine stays safe and effective. They charge samples into stability chambers, pull them at set intervals, test them for potency, impurities and other attributes, and trend the results over time. The role sits in quality control stability. A good one keeps the stability programme running on schedule, pulls and tests samples exactly on protocol, produces accurate trended data, and flags any out-of-trend or out-of-specification result early so the shelf life of products can be trusted.

Managing a Stability Analyst in ZeniaHR

AttendanceSet a general or lab shift with biometric punches at the lab gate, since analysts gown up for the QC lab. Sample pulls are time-bound, so the monthly summary feeds payroll after month close, and comp-off can be granted for weekend pulls or testing.LeavePlan leave around the stability pull schedule, since pulls cannot be missed or delayed, and arrange cover before going away. The leave calendar helps make sure scheduled pulls and testing are never left uncovered while the analyst is away.Performance and KRAsEnter the KRAs above as weighted goals in a quarterly review cycle, with schedule adherence and test accuracy weighted highest. Run the probation review rated by the stability head, and review data integrity and reporting each quarter.

Frequently asked questions

What does a stability analyst do?

A stability analyst runs the stability studies that prove how long a medicine stays safe and effective. They charge samples into stability chambers, pull them at set intervals, test them for potency, impurities and other attributes, and trend the results over time. They keep the programme on schedule and flag any out-of-trend result early.

What is a stability study in pharma?

A stability study stores a medicine under set temperature and humidity conditions and tests it at intervals over months or years to see how its quality changes. The data sets the product's shelf life and storage conditions. Stability analysts run these studies, pulling and testing samples exactly on the protocol schedule.

What qualifications do you need to be a stability analyst?

An M.Pharm or MSc in chemistry or a related science is the usual requirement, with knowledge of stability testing and analytical methods like HPLC. Understanding of good laboratory practice and data integrity is essential. Employers hire freshers with a strong analytical base and train them on the stability programme and protocols.
