We know trust starts in the lab. This page outlines the standards, methods, and controls we use to verify identity, purity, and consistency of research-grade materials—so your experiments begin with reliable inputs.

Our quality principles

• Research-grade focus: Materials are released against rigorous, fit-for-purpose specifications for laboratory use only—never for human or veterinary application.
• Method transparency: Every lot’s Certificate of Analysis (CoA) discloses identity methods, assay conditions, and key parameters so you can mirror or evaluate suitability.
• Traceability by design: End-to-end lot records connect receiving, testing, release, and distribution events for auditable provenance.
• Continuous improvement: Methods evolve through data, robustness checks, and change control; version history preserves continuity.

Identity confirmation

• Primary techniques:
  LC–MS/GC–MS: Mass-to-charge confirmation and impurity screening for volatile/nonvolatile profiles.
  NMR (1H/13C): Structural verification against reference spectra.
  FTIR/UV–Vis: Functional group fingerprints and complementary identity confirmation.
• Acceptance criteria:
  Spectral match: Within predefined tolerances to reference standards.
  Orthogonality: Secondary confirmation (e.g., NMR + FTIR) used when structural ambiguity is possible.
  Form verification: Salt/base form and, where applicable, polymorph tags are verified.

Purity, impurities, and residuals

• Assay (HPLC/UHPLC):
  Reporting: Area percent with release specification; peak purity checks confirm spectral homogeneity.
  System suitability: Resolution, tailing factor, theoretical plates, and %RSD for replicate injections are documented.
• Impurity profile:
  Identified/unknowns: Quantified with reporting thresholds; non-detects are contextualized to method LOQ.
  Chiral purity: Specific rotation and/or chiral HPLC provide enantiomeric excess (ee%) when applicable.
• Residual solvents and inorganic:
  Solvents: Quantified versus internal limits; GLP-style disclosure of LOQ for non-detect entries.
  Elemental (CHN): Confirms empirical composition; heavy metals screening added where relevant.
• Moisture and solid-state:
  Karl Fischer: Percent water (w/w) for hygroscopic materials.
  XRPD/DSC/TGA: Polymorph fingerprinting and thermal event mapping for stability insights.

Method validation and performance

• Specificity and selectivity:
  Controls: Interference checks, matrix evaluation, and orthogonal identity paths to avoid false positives.
• Precision and accuracy:
  Metrics: Repeatability/reproducibility (%RSD), recovery studies for complex matrices, and calibration curve linearity verification.
• Robustness:
  Stress tests: Minor parameter shifts (flow, temperature, pH, gradient) are assessed to ensure method resilience.
• LOD/LOQ transparency:
  Context: Detection/quantitation limits reported for identity and impurity methods to anchor interpretation of “non-detect.”
• System suitability (day-of-run):
  Checklist: Retention time stability, plate count, resolution of critical pairs, tailing/asymmetry, and injection precision.

Documentation and data integrity

• CoA package:
  Contents: Lot metadata, identity methods and spectra, chromatograms, assay results, impurity tables, residuals, moisture, solid-state data, storage guidance, and signatures.
• SOPs and references:
  Access: Method IDs, instrument models, column chemistry, mobile phases, gradients, and validation summaries.
• Version control and audit trails:
  Records: Document IDs, amendment logs, and change-control summaries maintain historical fidelity.
• File authenticity:
  Checksum: Cryptographic fingerprinting on PDFs; packaging QR resolves to the exact lot’s record.

Storage, stability, and handling

• Storage guidance:
  Conditions: Temperature range, light protection, desiccation, inert atmosphere, and packaging format per lot.
• Retest dates and shelf life:
  Policy: Retest dates prompt re-evaluation; shelf life reflects expected in-spec performance under recommended storage.
• Risk mitigation:
  Notes: Hygroscopic, photolabile, thermolabile, or volatile materials carry heightened handling cautions in the CoA.

Quality incidents, CAPA, and escalation

• Incident reporting:
  Information: Lot number, product name, observation details, photos/data, and storage conditions expedite investigation.
• Root-cause and CAPA:
  Outcome: Structured analysis with corrective and preventive actions; documented resolutions linked to the lot record.
• Escalation path:
  Access: QA review within defined timelines; manager escalation available for time-sensitive cases.
