Impurity reference standards
Finerenone impurity standards
For Finerenone, the Zemixal catalogue holds 26 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Counted by type, there are 3 metabolites or hydroxylated analogues and 2 degradation products.
26reference materials
3metabolites
2degradants
Each lot ships with a certificate of analysis, and characterisation data such as 1H-NMR, mass spectrum and HPLC purity can be shared before you order. They are bought for system suitability, peak identification, quantitation against limits and the impurity justification sections of regulatory submissions.
By impurity type
Metabolites3Hydroxy, desmethyl and conjugated forms
Degradants2N-oxides, dimers, lactones and breakdown products
Counts are based on product names. One compound can fall into more than one type.

Questions
Finerenone impurities, answered
What Finerenone reference materials are available?
The catalogue currently lists 26 compounds for Finerenone, including 3 metabolites or hydroxylated analogues and 2 degradation products. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Finerenone impurity standard?
A certificate of analysis travels with every lot. On request we share the characterisation set, usually 1H-NMR, mass spectrum, HPLC purity and IR, and for some materials TGA or water content. Ask for the data before ordering if your QA team needs to review it.
Can Zemixal make a Finerenone impurity that is not listed?
Often yes. Send the structure, name or CAS number with the quantity you need and our sourcing team checks custom synthesis options, usually from 10 mg up to gram scale, with a quoted lead time.
