In the vast landscape of chemistry, precise identification of compounds is crucial for research, manufacturing, and regulatory compliance. The Chemical Abstracts Service (CAS) Registry Number is a unique numerical identifier assigned to every chemical substance described in the open literature. These CAS numbers are indispensable for avoiding ambiguity and ensuring that researchers and manufacturers are referring to the exact same chemical entity. Today, we will delve into the importance of CAS numbers by examining trans-4-cyclohexyl-L-proline hydrochloride, identified by CAS No. 90657-55-9.

The CAS Registry Number, 90657-55-9, serves as a universal reference for trans-4-cyclohexyl-L-proline hydrochloride. This compound, a white powder, is highly valued as a pharmaceutical intermediate. Its primary application lies in the synthesis of Gefitinib, an important medication used in cancer therapy. For scientists and procurement specialists in the pharmaceutical industry, referencing the correct CAS number is vital to ensure they are sourcing the precise chemical required for their synthesis pathways. Using the correct CAS number prevents costly errors and ensures the integrity of the manufacturing process.

The meticulous nature of pharmaceutical production demands that every starting material and intermediate meet rigorous standards. trans-4-cyclohexyl-L-proline hydrochloride, when sourced, must conform to specified purity levels, typically assayed at 98.0% or higher. This level of purity is critical for the successful synthesis of Gefitinib, as impurities can affect reaction yields, lead to unwanted byproducts, and compromise the safety and efficacy of the final drug. Therefore, a reliable supplier will always provide detailed specifications alongside the CAS number.

When you search for this critical component, using its CAS number, 90657-55-9, will help you find reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. who specialize in high-quality pharmaceutical intermediates. Understanding the significance of CAS numbers is part of a broader commitment to quality and precision in chemical procurement. It is a foundational element that underpins the successful operation of research laboratories and large-scale manufacturing facilities alike.

The global chemical industry relies on systems like the CAS Registry to maintain order and facilitate communication. By standardizing chemical identification, CAS numbers streamline processes from laboratory research to international trade, making them an invisible yet indispensable tool for progress in chemistry and medicine.
