Dutasteride

When sourcing Dutasteride as an Active Pharmaceutical Ingredient (API), buyers must prioritize purity levels of ≥98% or ≥99% as confirmed by HPLC (High-Performance Liquid Chromatography). It is essential to verify the CAS Number (164656-23-9) to ensure chemical accuracy. Suppliers should provide a detailed Certificate of Analysis (COA) for every batch, specifying melting point, heavy metal content, and residual solvents to ensure the product meets USP or EP (European Pharmacopoeia) standards.

Due to its nature as a potent chemical/pharmaceutical substance, you must ensure the supplier holds a GMP (Good Manufacturing Practice) certification. For smooth customs clearance, request the MSDS (Material Safety Data Sheet) and a Technical Data Sheet (TDS). If the product is intended for regulated markets, check for a DMF (Drug Master File) registration. Always ensure the supplier complies with REACH regulations if exporting to the EU.

Dutasteride is sensitive to environmental factors. It should be stored in cool, dry conditions (typically 2-8°C or room temperature below 25°C) and protected from light. Ensure the supplier uses vacuum-sealed, light-resistant aluminum foil bags or high-density polyethylene (HDPE) drums. For cross-border shipping, verify that the packaging is robust enough to prevent moisture ingress and physical degradation during long-transit periods.

B2B buyers typically procure Dutasteride for pharmaceutical formulation, specifically for treating Benign Prostatic Hyperplasia (BPH) and Androgenetic Alopecia (male pattern hair loss). It functions as a dual 5-alpha-reductase inhibitor, blocking both Type I and Type II enzymes. Buyers in the R&D sector use it for chemical synthesis and laboratory trials, requiring high-grade analytical reagents.

Always conduct third-party laboratory testing (e.g., SGS or Intertek) before final payment. Use Made-in-China.com’s audited supplier system to verify the manufacturer's physical existence and production capacity. Avoid deals that offer prices significantly below the market average, as this often indicates diluted or impure material.

Focus on long-term volume contracts rather than one-off spot purchases to secure a 10-20% discount. Negotiate for staggered delivery schedules to ensure fresh batches. Request free samples (5-10g) for initial lab testing, but offer to cover the express shipping costs to demonstrate serious intent.

Dutasteride is often classified as a sensitive powder. Use specialized chemical couriers who are experienced in handling 'sensitive goods' to avoid customs seizures. Ensure the HS Code (typically 293729) is correctly declared. For large volumes, Air Freight is preferred over Sea Freight to minimize exposure to extreme temperature fluctuations in shipping containers.

Utilize secure payment terms such as Letter of Credit (L/C) or Trade Assurance services provided by Made-in-China.com. Never wire full payments to personal bank accounts; always ensure the beneficiary name matches the company name on the business license and the proforma invoice.
