Manufacturing Process
Impurity standards are synthesised using routes designed to produce material with defined chemical purity and a fully characterised structure. Synthesis strategies prioritise isolation of the target impurity or its closest structural equivalent for use as a reference standard in analytical methods.
Each batch undergoes structural confirmation and purity assessment through a suite of analytical techniques. PEC Pharma's quality-controlled laboratory infrastructure supports the data package required for customer method qualification and regulatory submissions.
For nitroso and genotoxic impurity classes, dedicated synthetic and analytical approaches are applied to meet the sensitivity and trace-level detection requirements of modern pharmaceutical quality standards.
