In the vast and complex world of chemistry, precise identification of substances is not just a matter of convenience but a fundamental requirement for safety, research, and commerce. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as a unique, universal identifier for chemical substances. This article aims to elucidate the significance of CAS numbers, particularly for researchers and procurement professionals dealing with specialized chemical compounds like Fmoc-L-4-Trifluoromethylphenylalanine, and emphasize the importance of sourcing from reliable manufacturers.

A CAS number is a string of digits, separated by hyphens into three parts, that unequivocally identifies a specific chemical compound, polymer, or biological sequence. For instance, Fmoc-L-4-Trifluoromethylphenylalanine is officially registered under CAS number 247113-86-6. This number is independent of any trade names, brand names, or company-specific product codes. It acts as a standardized reference, crucial for avoiding ambiguity in scientific literature, safety data sheets (SDS), regulatory documentation, and procurement processes.

The value of a CAS number extends across various applications. In research and development, it ensures that scientists are working with the correct material, preventing costly errors and ensuring the reproducibility of experiments. For procurement managers, a CAS number is an indispensable tool when placing orders. It allows for precise specification of the desired chemical, reducing the risk of ordering the wrong substance, especially when dealing with a broad catalog of similar compounds. For example, knowing the CAS number for Fmoc-L-4-Trifluoromethylphenylalanine ensures you receive the correct L-isomer with the trifluoromethyl group at the specified position.

When you intend to buy chemicals like Fmoc-L-4-Trifluoromethylphenylalanine, always verify the CAS number provided by the supplier. Reputable manufacturers and suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., will prominently display the correct CAS number alongside the chemical name and other specifications like purity and appearance (e.g., white to off-white solid or powder). This transparency is a hallmark of a trustworthy supplier dedicated to product integrity.

The global chemical industry relies heavily on these unique identifiers for regulatory compliance, safety information dissemination, and efficient trade. Understanding and correctly using CAS numbers when requesting quotes or placing purchase orders for materials like amino acid derivatives is a critical skill for professionals in the chemical and pharmaceutical sectors. It underpins accurate communication between buyers and sellers, ensuring that the right product, at the specified quality, reaches its destination.

In conclusion, CAS numbers are fundamental to the precise identification and safe handling of chemical substances. They provide an unambiguous reference point for chemists, researchers, and procurement specialists worldwide. By prioritizing suppliers who clearly and accurately provide CAS numbers, such as NINGBO INNO PHARMCHEM CO.,LTD. for products like Fmoc-L-4-Trifluoromethylphenylalanine, you safeguard the integrity of your research and procurement processes.
