Frequently Asked Questions
What is the standard yield range in pharmaceutical manufacturing?
While it varies by product and process stage, a standard acceptable range is often between 95% and 105%. Yields outside this range typically trigger an investigation into potential process errors or material losses.
How do I calculate theoretical yield for a multi-step reaction?
For multi-step processes, the cumulative theoretical yield is calculated by multiplying the theoretical yields of each individual step. This tool helps you verify the yield at each specific stage.
Can a yield ever be exactly 100%?
While theoretically possible, in practical pharmaceutical manufacturing, some loss is expected due to equipment holdup, evaporation, or transfer. A value significantly exceeding 100% may indicate impurities or moisture.
Does this tool store my batch data?
No. We prioritize data security and proprietary privacy. All data entry and calculations are processed entirely within your web browser. No information is ever sent to or stored on our servers.
