Alizurol Purple Procurement Checklist for Bulk Buyers

Introduction Buying Alizurol Purple in bulk requires more than comparing price and pack size. For cosmetic, pharmaceutical, or other regulated applications, the wrong grade can create problems with formulation, testing, documentation, and market compliance.  There is also an important naming issue. Alizurol Purple can refer to different anthraquinone colorants in industry sources. For example, the FDA identifies Alizurol Purple with D&C Violet No. 2, CAS 81-48-1 and CI 60725. Other technical sources identify Alizurol Purple as Ext. D&C Violet No. 2, CAS 4430-18-6 and CI 60730. For this reason, bulk buyers should confirm the exact identity before requesting samples or placing a purchase order. Alizurol Purple Bulk Procurement Checklist 1. Confirm the Exact Product Identity Do not approve a supplier based only on the name “Alizurol Purple.” Ask the supplier to provide: Chemical name CAS number Color Index number Molecular formula and molecular weight Product grade Country of manufacture Intended application For example, FDA records list D&C Violet No. 2 as CAS 81-48-1 and identify Alizurol Purple among its other names. If a supplier gives you a different CAS or CI number, do not assume it is an equivalent product. Investigate the difference first. 2. Check the Regulatory Status Regulatory
