Overview
A CAS number is a unique identifier assigned by the Chemical Abstracts Service (CAS) to every chemical substance described in the open scientific literature. The CAS number 4521200 is one such identifier, though the specific chemical it refers to is not detailed here. CAS numbers are essential in chemical research, regulatory compliance, and commercial transactions, providing a standardized way to reference substances globally. CAS numbers are widely used in databases, safety data sheets (SDS), and regulatory documents to avoid confusion caused by varying chemical names or synonyms. They consist of up to ten digits, divided into three parts by hyphens, with the last digit serving as a check digit to ensure validity.
Physical and Chemical Properties
Since 4521200 is a CAS number rather than a specific chemical, its physical and chemical properties depend on the substance it identifies. CAS numbers do not convey properties themselves but serve as a reference to lookup detailed information in chemical databases or regulatory lists. For accurate data on the substance associated with CAS 4521200, consult authoritative sources like the CAS Registry, PubChem, or supplier-provided technical data sheets. These resources provide molecular formulas, weights, and other critical properties necessary for safe handling and application.
Main Applications
CAS numbers like 4521200 are primarily used for unambiguous chemical identification in scientific research, industrial applications, and regulatory frameworks. They help streamline chemical inventory management, ensuring accurate tracking and compliance with global regulations such as REACH, TSCA, or GHS. In B2B contexts, CAS numbers facilitate precise communication between suppliers and buyers, reducing errors in procurement and logistics. They are also critical in safety documentation, enabling quick access to hazard and handling information for workers and emergency responders.
Safety and Storage
Safety and storage guidelines for a chemical associated with CAS 4521200 would depend on its specific properties. Without knowing the exact substance, general best practices include consulting Safety Data Sheets (SDS) for hazard information, proper labeling, and adherence to local regulatory requirements. Storage conditions must align with the chemical’s stability—factors like temperature sensitivity, reactivity, and compatibility with container materials should be evaluated. Always use appropriate personal protective equipment (PPE) and follow institutional or industry-specific safety protocols when handling unidentified or poorly characterized chemicals.
B2B Procurement Guide
When procuring chemicals using CAS numbers like 4521200, verify the number’s accuracy with reliable databases or suppliers to avoid misidentification. Cross-check synonyms, molecular formulas, and other identifiers to ensure the correct substance is sourced. Consider regulatory status, as some chemicals may be restricted or require special permits. Establish relationships with reputable suppliers who provide comprehensive documentation, including CAS-number-linked SDS and certificates of analysis (CoA). Pricing varies widely based on purity, quantity, and market demand, so request quotations from multiple vendors for comparison.
