when we manufactured any api batch and having time cycle for 5 days and in between month change can give batch mfg date as after drying ?
Batch Manufacturing date should be assigned according to internal SOP.
In some companies, the manufacturing date is defined as date of charging of Raw materials into reactor for synthesis of that particular stage (Intermediate). OR in case of the final stage of API manufacturing it is the date of crystallization of that API (Final stage). There should not be any change of date of manufacturing if there is a change in the month during the processing.
Okay,thanks for reply
