Day-to-Day Responsibilities
Reviews the existing synthesis route for a drug and identifies steps that are unsafe, slow, low-yielding or costly.
Designs and runs laboratory and pilot-scale trials to test alternative reagents, solvents, temperatures and reaction times.
Measures yield, purity and impurity levels, and works with analytical chemists to confirm results.
Carries out safety assessments of reactions, such as heat release and gas evolution, and recommends controls.
Writes and updates process descriptions, batch records and technical reports that plant and quality teams follow.
Supports technology transfer, where a validated method moves from development into a commercial plant, and reviews batch deviations when they occur.
