For procurement managers and R&D scientists in the pharmaceutical and nutraceutical industries, a thorough understanding of ingredient specifications is non-negotiable. Atractylenolide-1 (CAS 73069-13-3) is a powerful botanical derivative with significant therapeutic potential, particularly for digestive health. This article delves into the critical quality aspects and specifications that buyers should scrutinize when sourcing this compound from manufacturers.

The primary identifier for Atractylenolide-1 is its CAS number: 73069-13-3. This unique numerical designation ensures that you are procuring the correct chemical entity. When communicating with a potential manufacturer or supplier, always confirm this CAS number is accurately listed on all documentation, including quotes and Certificates of Analysis (CoA).

A key quality indicator for Atractylenolide-1 is its appearance. Typically supplied as a 'White crystalline powder,' any deviation from this description should be a point of inquiry. The physical form directly impacts handling, solubility, and integration into various formulations.

Crucially, the assay percentage dictates the concentration of the active compound. For Atractylenolide-1, an assay of '≥ 98.0%' is considered industry standard for high-purity applications. Lower percentages may indicate impurities or degradation, potentially affecting the efficacy and safety of the final product. Buyers should always request a CoA that clearly states the assay results for each batch purchased.

When discussing price, remember that the purity and consistency of Atractylenolide-1 are significant cost drivers. A reliable manufacturer in China will be transparent about these specifications and how they influence the overall price. It is advisable to obtain quotes for specific quality grades that align with your application requirements, whether for pharmaceutical intermediates or functional ingredients.

Storage and packing conditions are also vital for maintaining product integrity. Proper storage in a cool, dry place, as recommended by suppliers, helps prevent degradation. Packaging, often in 1kg bags or customized according to client needs, should protect the powder from moisture and contamination during transit. Understanding these details ensures that the Atractylenolide-1 you purchase arrives in optimal condition, ready for your critical applications.

By meticulously reviewing these specifications and partnering with reputable manufacturers and suppliers, B2B buyers can confidently procure Atractylenolide-1 that meets rigorous quality standards, thereby safeguarding the integrity and performance of their end products.
