Batches are supplied with a certificate of analysis, and the supporting spectra can be sent ahead of a purchase order so your QA team can review them. Typical uses are method development and validation, relative response factor work, forced degradation studies and the impurity sections of ANDA, DMF or CEP filings. For nitrosamine risk evaluation, the N-nitroso standards allow confirmatory LC-MS testing against the acceptable intake limits.

Questions

Nadolol impurities, answered

What Nadolol reference materials are available?
The catalogue currently lists 9 compounds for Nadolol, including 3 pharmacopoeial impurities and 1 nitrosamine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Nadolol 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 Nadolol 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.
Do you supply Nadolol nitrosamine impurities?
Yes. 1 N-nitroso compound is listed for Nadolol. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
