QC Workflow
From procurement to shipment — a documented chain of custody.
Every lot passes through a six-stage quality process before leaving our facility. No product ships without passing each stage.
Procurement
Materials sourced from qualified synthesis facilities with documented origin.
Identity Verification
ESI-MS confirms molecular identity and mass against theoretical values.
Purity Analysis
RP-HPLC quantifies purity against acceptance criteria (≥98%).
COA Generation
Lot-specific COA issued with all analytical results and specifications.
Batch Retention
Reference sample from each lot archived for minimum 24 months.
Fulfillment QC
Pre-shipment inspection confirms packaging, labeling, and cold chain compliance.
Analytical Testing
Third-party identity and purity verification.
All analytical testing is performed by independent accredited laboratories. Results are issued on letterhead and retained as part of the lot documentation package.
RP-HPLC
Purity AnalysisMethod: Reversed-phase high-performance liquid chromatography
Column: C18 analytical column
Acceptance criterion: ≥98% area purity
ESI-MS
Identity ConfirmationMethod: Electrospray ionization mass spectrometry
Output: Observed vs. theoretical molecular mass
Acceptance criterion: Mass match within ±0.5 Da
