Impurity reference standards
Aspartic acid impurity standards
For Aspartic acid, the Zemixal catalogue holds 7 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Most entries are process-related impurities, synthesis intermediates and isomers.
7reference materials
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.

Questions
Aspartic acid impurities, answered
What Aspartic acid reference materials are available?
The catalogue currently lists 7 compounds for Aspartic acid. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Aspartic acid 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 Aspartic acid 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.
