Azobisformamide is a low molecular weight a gem used in the plastic industry as a foaming product. Two subjects with a history of work-related asthma in association with exposure to azobisformamide underwent specific inhalation tests. One subject developed an isolated late asthmatic response, whereas in the other a dual reaction was observed.
