In the complex landscape of chemical manufacturing and trade, precise identification and clear communication are foundational to success. Among the most critical tools for achieving this is the Chemical Abstracts Service (CAS) Registry Number. These unique numerical identifiers play an indispensable role in the global chemical industry, ensuring that researchers, manufacturers, and regulators are referring to the exact same substance.

For instance, when businesses look to buy 7-nitroindole-3-carboxyaldehyde, specifying its CAS number, 10553-14-7, is non-negotiable. This numerical tag removes ambiguity, as a single chemical compound is assigned only one CAS number, regardless of its synonyms, trade names, or different manufacturing processes. This accuracy is vital when sourcing critical synthesis material intermediates, as even minor structural variations can significantly alter a compound's properties and suitability for a particular application.

A reliable manufacturer in China, or any other region, will invariably use CAS numbers as a primary means of identifying products in their catalogs, safety data sheets (SDS), and quotations. For a buyer, using the correct CAS number when requesting information or placing an order, such as for 7-Nitroindole-3-carboxyaldehyde (CAS 10553-14-7), helps to confirm that the correct material is being quoted and ultimately supplied. This diligence helps avoid costly errors and ensures that the procured chemicals, like pharmaceutical intermediates, meet stringent purity requirements (e.g., 97% minimum).

Moreover, CAS numbers facilitate efficient communication throughout the supply chain. When a buyer seeks a competitive price for a specific chemical, referencing the CAS number ensures that all potential suppliers are quoting for the identical substance. This streamlines the procurement process and allows for more accurate comparisons between different vendors. A reputable supplier will also use CAS numbers internally to manage inventory and ensure proper handling and storage, such as maintaining 7-Nitroindole-3-carboxyaldehyde under inert gas at 2-8°C.

In conclusion, CAS numbers like 10553-14-7 are more than just identifiers; they are essential facilitators of accuracy, clarity, and efficiency in chemical sourcing. By consistently using and verifying CAS numbers when engaging with manufacturers and suppliers, businesses can significantly enhance the reliability and success of their chemical procurement operations.
