For any B2B professional involved in procurement or product development, thoroughly understanding the specifications of a chemical compound is the first step towards a successful purchase. 1,2-Cyclohexylenedinitrilotetraacetic Acid (CDTA), a compound with the CAS number 13291-61-7, is no exception. Whether you are a pharmaceutical scientist, a research chemist, or a procurement manager, grasping its key attributes ensures you procure the right material for your specific needs. This guide breaks down the essential specifications of CDTA and explains their significance for buyers.

Defining the Compound: Chemical Name, Formula, and CAS Number

The precise identification of a chemical is fundamental. 1,2-Cyclohexylenedinitrilotetraacetic Acid, often referred to as CDTA, is the primary chemical name. Its CAS number, 13291-61-7, is a unique numerical identifier used globally to identify chemical substances. The molecular formula, C14H22N2O8, reveals the elemental composition and structure, providing insights into its chemical behavior. For a buyer, confirming these details is the initial verification step when comparing products from different suppliers, ensuring you are looking at the correct compound.

Purity and Assay: The Hallmark of Quality for CDTA

The most critical specification for 1,2-Cyclohexylenedinitrilotetraacetic Acid, particularly when it's intended for pharmaceutical intermediate use, is its purity. High-purity CDTA typically has an assay of ≥99%, sometimes reaching 99.5% MIN. This high assay indicates a minimal presence of impurities, which is vital for predictable reaction outcomes and the safety and efficacy of the final pharmaceutical product. Buyers should always request the Certificate of Analysis (CoA) from the manufacturer, which details the assay and other critical impurity profiles. A reliable supplier, such as a dedicated manufacturer in China, will readily provide this crucial documentation.

Physical Characteristics and Packaging

Understanding the physical form of CDTA is also important for handling and storage. It is commonly described as a white or off-white powder. This characteristic influences how it is packaged and shipped. Standard packaging options often include 25kg drums, suitable for bulk purchases. For R&D purposes or smaller production runs, alternative quantities might be available. Procurement managers should confirm the packaging options and minimum order quantities (MOQ) with the supplier to align with their project scale and inventory management strategies.

Applications and Certifications: Guiding Your Purchase Decision

While the primary application for high-purity CDTA is as a pharmaceutical intermediate, its chelating properties may lend it to other specialized chemical uses. Buyers often seek manufacturers who can confirm its suitability for their intended application, possibly supported by certifications such as GMP, USP, BP, EP, or FCC standards. These certifications are strong indicators of a product's quality and regulatory compliance, especially for industries with strict oversight. When considering a purchase, discussing your specific application with the supplier can help ensure you are selecting the most appropriate grade and quality of 1,2-Cyclohexylenedinitrilotetraacetic Acid.

In Summary: Informed Purchasing for B2B Success

By carefully examining the chemical name, CAS number, molecular formula, assay, physical properties, and relevant certifications, buyers can make informed decisions when purchasing 1,2-Cyclohexylenedinitrilotetraacetic Acid. Partnering with reputable manufacturers and suppliers who provide comprehensive specification data and support is key to ensuring the quality and reliability of this essential chemical intermediate for your downstream processes.
