Frequently asked questions

Common questions about this compound's patent and research landscape, answered from the underlying data.

What is the molecular composition of azodicarbonamide?

Azodicarbonamide has the molecular formula C2H4N4O2 with a molecular weight of 116.08. It is also known by the systematic name carbamoyliminourea and the InChI Key XOZUGNYVDXMRKW-UHFFFAOYSA-N.

Which companies hold the most patents related to azodicarbonamide?

Sekisui Chemical Co Ltd leads with 2251 patents, followed by Mitsui Chemicals Inc with 990 patents and Dow Global Technologies LLC with 958 patents. Other significant patent holders include Sekisui Kasei Co Ltd (866 patents), 3M Innovative Properties Co (726 patents), and Bridgestone Corp (693 patents).

What are the primary industrial applications of azodicarbonamide based on patent classifications?

The dominant patent classifications indicate azodicarbonamide is primarily used in polymer processing. The top classification is C08J (macromolecular compounds - production or chemical treatment) with 17779 patents, followed by C08L (polymer compositions) with 14657 patents, and C08K (fillers, reinforcing agents) with 11101 patents. This reflects its major use as a blowing agent and processing additive in polymer foaming applications.

What thermal decomposition hazard has been identified for azodicarbonamide in food contact applications?

Research documented that semicarbazide is a minor thermal decomposition product of azodicarbonamide used in gaskets of certain food jars. This finding was significant enough to warrant development of enzyme immunoassay methods for detecting semicarbazide as a food contaminant and metabolite.

What was the patent activity trend for azodicarbonamide in recent years?

Patent filings showed sustained activity with 2704 patents in 2022 and 2869 in 2023. The three-year period (2022-2024) averaged approximately 2735 patents annually. Activity declined in 2025 with 1448 patents through the data collection point, reflecting partial-year reporting.
