Rodinal Special Question

Somewhere I have a full bottle (plastic bottle) of the old Agfa Rodinal Special. What I remember is that it was similar to Kodak HC-110. Did it have the same shelf life as the old thick HC-110?

The old HC-110 was reputed to contain no water and that lead to its long life. Rodinal Special did contain some water according to the MSDS so maybe it's not likely to last so well. In my experience the Agfa plastic bottles were quite good. Liquid Neutol-WA in 1L plastic bottles lasted for many years.
