- Interpretation of results:
- other: non-flammable
- Conclusions:
- The mean flash point of 4-methoxyphenylacetic acid(CAS No. 104-01-8) is 191.6°C at 977.6hPa.
- Executive summary:
The flash point determination of 4-methoxyphenylacetic acid (CAS No. 104-01-8) was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 191.6°C at 977.6hPa. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the 4-methoxyphenylacetic acid (CAS No. 104-01 -8) was considered to be non-flammable.
