Phenacetin impurity standards
This page brings together 3 Phenacetin related compounds that analytical teams use to identify, quantify and control impurities in the active ingredient and the finished dosage form. Most entries are process-related impurities, synthesis intermediates and isomers.
3reference materials
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
Phenacetin impurities, answered
What Phenacetin reference materials are available?
The catalogue currently lists 3 compounds for Phenacetin. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Phenacetin 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 Phenacetin 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.
