Questions
Penoxsulam impurities, answered
How many Penoxsulam impurity standards does Zemixal list?
The catalogue currently lists 1 compounds for Penoxsulam. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Penoxsulam 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 Penoxsulam 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.
