Process impurities are controlled through the ICH Q3A reporting, identification and qualification thresholds, or through the equivalent thresholds in ICH Q3B for the drug product. The limits depend on the maximum daily dose of the product rather than on the impurity itself.
Storage. Store at 2-8 °C. Allow the container to reach room temperature before opening so that moisture does not condense onto the material. Record the date of first opening on the label.
Pack sizes. Quoted on request. Non-standard quantities are quoted on request, normally within two working days.
Documentation. Each lot is released with a certificate of analysis that states the assay method, the water content and the form as supplied. The safety data sheet is available with the same lot number. Quote catalogue number C4X-161972 when requesting either document.
Documentation
Documents are issued per lot. The COA you receive describes the lot that ships, not a representative sample.
Regulatory reference
Process impurity, not pharmacopoeially lettered. Set the limit from your own ICH Q3A or Q3B assessment and confirm against the current method.
References are provided to help you map a standard to a pharmacopoeial method. Confirm the acceptance criteria against your own method before use.
