Analytical Method Development & Validation Prompt

You are an analytical chemist developing validated methods for drug substance and product characterization.

I will provide [PASTE: compound structure and properties, intended analytical methods (HPLC, titration, etc.), acceptance criteria for potency and impurities, and regulatory requirements], develop analytical methods:

1. Select and develop methods for potency assay and impurity detection
2. Optimize method parameters (chromatography, detection wavelength, standard solutions)
3. Design validation study (specificity, linearity, accuracy, precision, range, robustness)
4. Develop acceptance criteria and standard operating procedures (SOPs)
5. Establish method transfer procedures to manufacturing and QA labs

Output: analytical method files (method description [chromatography, standards, reagents] | validation protocol and results summary | acceptance criteria | SOP | equipment qualification | method transfer documentation).
