Analytical Services

The analytical testing methods used to monitor potency and purity for raw materials, drug substances and drug products are primary views into the quality of materials. Redox Scientific focuses on efficiently developing robust and high- quality analytical methods that deliver reliable results. We have a vast range of capabilities in instrumentation and detectors. We employ a phase appropriate validation strategy to support programs from early clinical to commercial. Our team of experts has a proven reputation for taking on tough challenges and delivering a quality method to our customers.

Stability / Photo Stability Studies

  • Redox Scientific has experienced team capable to lead the process from protocol design to storage, monitoring, analytical testing and documentation.
  • A complete range of storage conditions in multiple climatic chambers.
  • The stability units have operational back-ups and are fully controlled with 24×7 monitoring and alert systems.
  • Customer-specific conditions can also be accommodated.
  • Long term and Stress conditions (accelerated). Drug products, drug substance intermediates hold time study.
  • Photo stability studies.

Trace Metal Analysis ( ICP-MS / LCP-OPS )

Trace metal impurities in pharmaceutical products are determined to prevent their harmful effects on patients.

  • We offer elemental analysis using ICP-MS for trace metal analysis.
  • ICP- MS is used to assay trace and ultra-trace elements at part per billion (ppb) levels

Residual Genotoxic Impurity Studies ( GC-MS / LC-MS / MS )

  • Genotoxins (limits less than 200 ppm) are challenging classes of impurities that have proven to be harmful even at low concentrations and as a result regulatory bodies have specifically defined their limits in drug substances and products.

Impurity Profiling

  • Isolate process related impurities and degradation products
  • Identify and characterize each impurity using modern analytical techniques
  • Synthesize identified impurities for further investigation and reference standards

Techniques We Use :

  • HPLC
