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.

Questions
Anastrozole impurities, answered
How many Anastrozole impurity standards does Zemixal list?
The catalogue currently lists 22 compounds for Anastrozole, including 8 pharmacopoeial impurities, 1 isotope-labelled standard, 1 metabolite or hydroxylated analogue and 1 degradation product. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Anastrozole 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 Anastrozole 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 Anastrozole standards available?
Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
