Description of key information

The test substance is light sensitive in dilute solution.

Additional information

The UV-VIS absorption of test substance have been measured and showed the maximum absorption (ɛ= 7953 L/mol/cm at 296 nm in methanol) occurs in the UV light range and some absorption (ca.ɛ=830 L/mol/cm) still occur in the violet light range of 380 nm. There was no detectable absorption above 450 nm.
