Baricitinib powder

For B2B procurement, Baricitinib (CAS No. 1187594-19-7) must meet a purity level of ≥99% as verified by HPLC (High-Performance Liquid Chromatography). Buyers should request a Certificate of Analysis (CoA) for every batch to confirm the absence of heavy metals (typically <10ppm) and residual solvents. The powder should appear as a white to off-white crystalline solid with a stable molecular weight of 371.37 g/mol.

Suppliers must operate under GMP (Good Manufacturing Practice) conditions. Depending on the target market, you should verify if the manufacturer holds a Drug Master File (DMF) number or CEP (Certificate of Suitability). For research or industrial use, ensure the supplier provides a Material Safety Data Sheet (MSDS) and complies with ISO 9001:2015 quality management systems.

Baricitinib is sensitive to environmental factors. It must be stored in cool, dry conditions (typically 2-8°C or -20°C for long-term stability) and protected from light. Ensure the supplier uses vacuum-sealed, light-resistant aluminum foil bags or high-density polyethylene (HDPE) drums. Stability testing data should be requested to understand the product's shelf life under specific transit conditions.

Baricitinib is a JAK1/JAK2 inhibitor. In a B2B context, it is primarily sourced for pharmaceutical formulation R&D, laboratory reagents, or the production of finished dosage forms for treating rheumatoid arthritis, alopecia areata, and certain inflammatory conditions. It is strictly for professional industrial or laboratory use and not for direct consumer consumption.

Always utilize Trade Assurance services provided by platforms like Made-in-China.com to protect your payment until delivery is confirmed. Conduct third-party inspections (such as SGS or Intertek) before shipment to verify the quantity and quality. Avoid using non-traceable payment methods like Western Union for initial transactions with new suppliers.

Pharmaceutical powders often face strict scrutiny. Ensure the HS Code (typically 2933.59) is correctly declared. You must provide a Non-Dangerous Goods Declaration or a DGM report for air freight. For shipping to countries with strict medical regulations (like the US or EU), ensure the importer has the necessary import licenses or DEA registrations to avoid customs seizure.

Negotiate based on tiered pricing (MOQ vs. Bulk). For Baricitinib, prices can drop significantly when moving from 100g samples to 1kg+ orders. Ask for a 'Price Match' guarantee against other GMP-certified labs and negotiate payment terms such as 30% deposit and 70% against the Bill of Lading (B/L) for established long-term partnerships.

Check the supplier's Business License and verify their factory location via video call or VR showroom. On Made-in-China.com, look for 'Audited Suppliers' who have undergone on-site verification by independent agencies. Request historical export data or references from previous international clients to confirm their reliability in the pharmaceutical sector.
