This unique melting point behavior of EMEROX® Azelaic Acid is but one example of how its odd carbon chain length makes azelaic acid different from other commercial dibasic acids. And since these differences are reflected by end-products, azelaic acid may give your product a competitive advantage ...or it may fit into your development program as a new dibasic acid from which to build unique products. Write Dept.C-9today for descriptive literature or a sample of Emerox Azelaic Acid.
