Importance of Raw Material and Finished Product Testing

In pharmaceutical manufacturing, material quality drives product quality. Comprehensive testing of raw materials and finished products is essential to ensure patient safety, product efficacy, and regulatory compliance. Every batch must meet strict purity and performance standards, while holding up to real-world scrutiny.

RMA is exclusively focused on pharmaceutical raw material and finished product testing. We provide compendial and client-specific analytical services backed by our world-class scientists. Robust quality systems ensure that our results are trustworthy enough to base your product’s infrastructure on. Our precise, defensible data helps strengthen supply chains and reduce manufacturing risk. In the end, that leads to confidence in your brand—from both healthcare professionals and patients.

Our Capabilities

RMA's analytical services are built to scale with your testing needs while maintaining accuracy, compliance, and audit-ready reporting. Our experienced scientists deliver reliable data to support routine operations and regulatory submissions.

We offer both compendial testing aligned with major global pharmacopeias (USP, EP, JP, BP, ChP, ACS) and non-compendial, client-specific methods tailored to unique products and regulatory requirements. Our services include:

  • Identity, purity, and assay testing 
  • Impurity and contaminant analysis 
  • Supplier qualification and material release 
  • Stability and retesting support 

As part of CS Analytical, RMA operates within a proven FDA-regulated, cGMP environment known for scientific rigor and regulatory leadership. Every test we perform is guided by the same commitment: providing you the ability to trust every stage of the product lifecycle.

Elemental Impurities Testing: Understanding USP <232>, USP <233>, and ICH Q3D

Elemental impurities in drug products can enter the manufacturing process through several pathways: as residual catalysts intentionally introduced during synthesis, as contaminants from interactions with processing equipment or container/closure systems, or as impurities already present in raw material components.  Unlike active pharmaceutical ingredients, elemental impurities provide no therapeutic benefit to patients. In fact, they can...
