Ferric Maltol

About Ferric Maltol

Ferric Maltol is an API reference standard carrying the CAS registry number 33725-54-1. Its molecular formula is C18H15FeO9 and its molecular weight is 431.2 g/mol. It is also known as Iron (III) maltol or maltol ferrique.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Good laboratory practice and suitable PPE are recommended during handling.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
