Irganox

Irganox Impurities

Irganox refers to a family of sterically hindered phenolic antioxidants widely used in polymers, plastics, adhesives, and packaging materials to prevent oxidative degradation. Impurities in Irganox compounds arise from synthetic processes, degradation under thermal or UV stress, and residual solvents or catalysts. These impurities are critical to monitor, especially in food-contact and pharmaceutical packaging applications, where safety and stability are paramount.

Irganox EP Impurities

We offer pharmacopeial and non-pharmacopeial Irganox impurity standards that conform to EP specifications. These are used in analytical method development, impurity profiling, and regulatory submissions. EP traceable compounds are available upon request and are supplied with validated analytical data including HPLC purity, NMR, and MS characterization.

Irganox Related Compounds

Our catalog includes structurally related compounds and degradation products associated with Irganox antioxidants. These are used in forced degradation studies, impurity identification, and toxicological qualification. All entries are supported by comprehensive analytical documentation and meet international regulatory expectations.

Irganox Impurity Reference Standards

Irganox impurity reference standards are supplied with validated analytical data including NMR, MS, and HPLC purity. These compounds are used in industrial R&D, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request. All products are re-tested at regular intervals to ensure consistency and reliability.
