Impurity reference standards
Nalidixic Acid impurity standards
For Nalidixic Acid, the Zemixal catalogue holds 1 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Counted by type, there are 1 isotope-labelled standard.
1reference materials
1isotope labelled
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. Laboratories use them to validate related-substance methods, set specification limits under ICH Q3A and Q3B, and identify unknown peaks in stability samples.

Questions
Nalidixic Acid impurities, answered
What Nalidixic Acid reference materials are available?
The catalogue currently lists 1 compounds for Nalidixic Acid, including 1 isotope-labelled standard. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Nalidixic 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 Nalidixic 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.
Are isotope-labelled Nalidixic Acid standards available?
Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
