Impurity reference standards
Indocyanine green impurity standards
This page brings together 7 Indocyanine green 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.
7reference 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. 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
Indocyanine green impurities, answered
What Indocyanine green reference materials are available?
The catalogue currently lists 7 compounds for Indocyanine green. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Indocyanine green 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 Indocyanine green 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.
