Cholic acid

When sourcing Cholic Acid (CAS No. 81-25-4), buyers must prioritize purity levels, typically requiring ≥98% or ≥99% for pharmaceutical and laboratory applications. Key technical parameters include melting point (197°C to 202°C), specific optical rotation (+33° to +36°), and loss on drying (≤0.5%). For high-end applications, ensure the heavy metal content is below 10ppm and that the product is a white to off-white crystalline powder free from visible impurities.

Compliance is critical as Cholic Acid is often used in the pharmaceutical and food industries. Buyers should verify that suppliers hold ISO 9001 for quality management and GMP (Good Manufacturing Practice) if the product is for medicinal use. For entry into specific markets, check for REACH registration (EU), FDA registration (USA), and COA (Certificate of Analysis) for every batch. If the source is bovine-derived, a BSE/TSE-free certificate is mandatory to ensure biological safety.

Cholic Acid is primarily used as an intermediate for the synthesis of Ursodeoxycholic Acid (UDCA) and other bile acid derivatives. It also serves as an emulsifier in the food industry and a solubilizing agent in biochemical research. Functional requirements include high solubility in alcohol and acetic acid and stable chemical reactivity for downstream synthesis. Buyers must ensure the particle size (mesh count) meets their specific formulation needs.

Cost-efficiency is achieved by balancing unit price against purity and lead times. Bulk orders (e.g., 100kg+) typically allow for discounts of 10-20%. Buyers should calculate the Total Cost of Ownership (TCO), including specialized chemical-grade packaging (fiber drums with double PE bags) and hazardous material handling fees if applicable. Sourcing from integrated manufacturers on Made-in-China.com can reduce costs by eliminating middleman markups.

The primary risks include quality inconsistency between samples and bulk cargo, and customs seizures due to improper labeling. To mitigate this, always request a Pre-Shipment Inspection (PSI) and ensure the supplier provides a comprehensive MSDS (Material Safety Data Sheet) in the destination country's language. Use secure payment terms like those offered on Made-in-China.com to protect your funds until delivery is confirmed.

Focus negotiations on price stability clauses and quality guarantees. Given the fluctuations in raw material costs (bile collection), aim for a fixed-price contract for 6-12 months. Demand a tiered pricing structure based on annual volume and negotiate for shorter lead times (ideally 7-14 days) for repeat orders to maintain lean inventory levels.

Cholic Acid should be shipped in cool, dry, and well-ventilated conditions to prevent degradation. Ensure the supplier uses UV-protected fiber drums and provides vacuum-sealed inner lining. For international shipping, confirm the HS Code (typically 291819) to determine accurate tariff rates and ensure the carrier is experienced in handling fine chemical powders to avoid cross-contamination.
