For procurement specialists and R&D scientists in the pharmaceutical and cosmetic industries, understanding chemical specifications is fundamental to sourcing the right materials. Retinoic Acid, also known as Tretinoin or Vitamin A Acid (CAS 302-79-4), is a critical ingredient with a wide range of applications. This guide aims to demystify its key specifications and highlight the advantages of sourcing this compound from reliable manufacturers and suppliers, particularly within China.

Key Specifications for Retinoic Acid (CAS 302-79-4)
When you intend to buy Retinoic Acid, several parameters are crucial to evaluate: CAS Number: The Chemical Abstracts Service (CAS) number, 302-79-4, is a unique identifier for Retinoic Acid. It ensures you are sourcing the correct chemical compound, essential for regulatory compliance and product accuracy. Purity: For cosmetic and pharmaceutical applications, high purity is paramount. Typically, Retinoic Acid is sourced with purity levels of 98% to 99% or higher, often specified as USP (United States Pharmacopeia) grade for pharmaceutical use. Appearance: Retinoic Acid is generally described as a yellow to yellow-orange crystalline powder. This visual characteristic is a basic check during quality assessment. Molecular Formula and Weight: C20H28O2 and a molecular weight of approximately 300.44 g/mol are standard identifiers. Solubility: Understanding its solubility in various solvents (e.g., soluble in DMSO, ethanol; insoluble in water) is vital for formulation development.

The Importance of Purity and Grade
The purity of Retinoic Acid directly impacts its efficacy and safety in final products. Impurities can lead to reduced effectiveness, unwanted side effects, or failure to meet regulatory standards. Therefore, sourcing from manufacturers who provide rigorous quality control and clear documentation, such as a Certificate of Analysis (CoA), is non-negotiable. The grade of Retinoic Acid—whether cosmetic, pharmaceutical, or research grade—dictates the level of scrutiny and the specific standards it must meet. For skincare products targeting acne or aging, cosmetic grade with high purity is usually sufficient, while pharmaceutical applications may require stricter USP or EP compliance.

Sourcing Retinoic Acid from China: A Strategic Choice
China's chemical industry offers a vast network of manufacturers and suppliers capable of producing high-purity Retinoic Acid at competitive prices. When looking to buy this compound, consider the following: Supplier Verification: Engage with suppliers who are transparent about their manufacturing processes, quality control measures, and export capabilities. Look for those with strong B2B platform profiles and positive customer reviews. Documentation: Ensure that suppliers can readily provide essential documents like CoAs, Material Safety Data Sheets (MSDS), and any necessary regulatory compliance statements. Bulk Purchasing Advantages: Chinese suppliers are often equipped to handle large-volume orders, providing significant cost savings for businesses that require substantial quantities of Retinoic Acid. Companies like NINGBO INNO PHARMCHEM CO.,LTD. can help connect you with these trusted sources. By understanding these specifications and leveraging the benefits of sourcing from China, businesses can secure a reliable supply of high-quality Retinoic Acid, ensuring the success of their product formulations.
