For professionals in the pharmaceutical and fine chemical industries, understanding the precise specifications of chemical intermediates is fundamental to successful research and manufacturing. (-)-EPICEDROL, known by its CAS number 19903-73-2, is one such compound where adherence to strict quality parameters is non-negotiable. This article outlines the key specifications buyers should look for when sourcing this important pharmaceutical intermediate.

Defining (-)-EPICEDROL: CAS 19903-73-2

(-)-EPICEDROL is a specific stereoisomer of cedrol, often derived from natural sources. Its chemical identity is confirmed by its CAS number 19903-73-2. The molecular formula C15H26O and a molecular weight of 222.37 provide its basic chemical composition. When engaging with a (-)-EPICEDROL supplier China, these identifiers are the first point of reference.

Critical Specification: Purity

The most critical specification for any pharmaceutical intermediate is its purity. For (-)-EPICEDROL, a minimum purity of 99% is generally required. This high level of purity ensures that the compound will perform predictably in complex synthetic reactions, minimizing side reactions and the formation of unwanted byproducts. Buyers should always request a Certificate of Analysis (CoA) from their chosen manufacturer that details the purity and the analytical methods employed (e.g., GC, HPLC). When you intend to buy (-)-EPICEDROL, always prioritize suppliers who can consistently deliver this high purity.

Appearance and Physical Properties

The standard appearance for (-)-EPICEDROL is a white solid. This physical state is advantageous for handling, weighing, and storage. Other physical properties, such as melting point, boiling point (approx. 277.2°C), and flash point (approx. 115.5°C), are also important for understanding its stability and safe handling procedures. These details are usually available in the product's Safety Data Sheet (SDS) and technical data sheets provided by the supplier.

Procurement Considerations

When you are ready to order pharmaceutical intermediates online or seek a reliable CAS 19903-73-2 manufacturer, ensure the supplier can provide comprehensive documentation. Beyond the CoA, look for information on storage conditions, stability data, and potential regulatory compliance. Discussing your specific project needs with the supplier can help ensure you are getting the most suitable grade of (-)-EPICEDROL. Engaging with a trusted supplier who understands the pharmaceutical industry's demands will streamline your procurement process and support your R&D efforts effectively.
