Niraparib impurity standards
Zemixal lists 15 reference materials related to Niraparib, covering the drug substance itself, its process impurities and the products it forms on storage. The list is made up mainly of process impurities, positional isomers and intermediates from common synthetic routes.
15reference 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. Typical uses are method development and validation, relative response factor work, forced degradation studies and the impurity sections of ANDA, DMF or CEP filings.

Questions
Niraparib impurities, answered
How many Niraparib impurity standards does Zemixal list?
The catalogue currently lists 15 compounds for Niraparib. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Niraparib 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 Niraparib 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.
