Impurity reference standards
Theobromine impurity standards
3 characterised compounds linked to Theobromine are catalogued here, from named pharmacopoeial impurities to synthesis intermediates and breakdown products. The list is made up mainly of process impurities, positional isomers and intermediates from common synthetic routes.
3reference materials
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
Theobromine impurities, answered
How many Theobromine impurity standards does Zemixal list?
The catalogue currently lists 3 compounds for Theobromine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Theobromine 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 Theobromine 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.
