Quality Control
Quality Control — Every Molecule Traceable from Raw Material to Final Product
We ensure every custom batch meets or exceeds your specified purity requirements and deliver a complete analytical data package to support customer audits and regulatory submissions.
At Beixinke Chem, our quality system ensures every custom batch meets your specified purity requirements. From raw material verification through in-process controls to final release, each product is rigorously analyzed by HPLC, LC-MS, and 400 MHz NMR. For chiral compounds, enantiomeric excess (ee) is determined by chiral HPLC or polarimetry. Every shipment includes a complete data package: COA, HPLC chromatograms, LC-MS spectra, and NMR plots—fully documented for your internal review and regulatory submission. All products are for research use only and not for human or therapeutic applications. Batch-to-batch consistency is maintained through documented SOPs and system suitability tests.
Quality Assurance Pillars
Every step, from raw material to final delivery, is strictly controlled to meet international standards.
Raw Material Testing
Incoming materials are verified against supplier COA and confirmed by in-house NMR/HPLC for structure and purity. Only spec-compliant materials proceed to production, ensuring quality at the source.
Standardized Process Control
Real-time reaction monitoring (TLC/HPLC) is conducted throughout synthesis. Key intermediates are qualified before proceeding. Strict SOP adherence ensures batch-to-batch consistency and reproducibility.
Finished Product Testing & Traceability
Each batch is analyzed by HPLC, LC-MS, and 400 MHz NMR. Chiral compounds undergo ee determination. A unique batch code enables full traceability from production to delivery.
Compliant Packaging & Storage
Products are appropriately packaged based on physicochemical properties for transport stability. Our warehouse features temperature and humidity controls to maintain optimal storage prior to delivery.
Reliable Delivery
Every shipment includes a complete data package: COA, HPLC, LC-MS, and NMR spectra. We partner with professional logistics providers for safe, on-time delivery to your lab.
Customer Feedback & Optimization
We value customer feedback, conduct regular project reviews and root-cause analysis, and continuously optimize synthetic routes and quality systems to elevate our service standards.
