Dear all,
Does anyone know the current UN# for Hydroquinone CAS# 123-31-9?
I was informed that below is the older UN#:
UN Number: 2662 (Class 6.1 Poison P.G. III)
Some MSDS (revised on 2008) for Hydroquinone 90-100% has a UN/NA: UN3077 and other MSDS made 2007 and below has UN #2662 (Class 6.1 Poison PG III). All other properties are the same (CAS, % purity, properties, etc) except for the UN#.
Please help.
Thank you,
