Ensuring identity, strength, quality, and purity for global regulatory compliance.
Pharmaceutical standards—including Primary Reference Standards, Secondary Working Standards, Impurity Standards, and Isotope-Labeled Standards—are critical for ensuring the identity, strength, quality, purity, and potency of Active Pharmaceutical Ingredients (APIs) and finished drug products.
Adherence to global pharmacopeial standards (USP, EP, JP, BP) and ISO guidelines (ISO 17034, ISO/IEC 17025) is mandatory across pharmaceutical research, quality control (QC), batch release, and stability testing.
| Standard Type | Primary Use & Purpose | Key Regulatory/Quality Requirement |
|---|---|---|
| Primary Reference Standards | Official baseline standards established by recognized pharmacopeias (USP, EP, BP). | Full structure characterization; direct traceability to international units. |
| Working (Secondary) Standards | Routine batch analysis, assay testing, and raw material qualification in QC labs. | Calibrated directly against a primary reference standard with a valid CoA. |
| Impurity Standards | Identification and quantification of process-related impurities and degradation products. | High purity (>95%), clear structure elucidation via NMR and LC-MS. |
| Stable Isotope-Labeled Standards | Internal standards (13C, 2H) for LC-MS/MS bioanalytical and trace analysis. | High isotopic purity with minimal un-labeled species interfering with target analytes. |
To meet regulatory audit requirements, every certified reference standard undergoes rigorous analytical evaluation to generate a comprehensive Certificate of Analysis (CoA).
