D-23 stock shelf life

Thanks. The one I have is from 1977.

And for what it's worth, my Kodak Publication J-1, 6th edition, 1963, first 1965 printing gives the following "Keeping properties without use":

Full stoppered bottle: 6 months
Half-full stoppered bottle: 2 months
Tray: 24 hours
Gallon tank: 1 month
This is for storage at 65-70º F, higher storage temperatures will give shorter life. And "The figures given in this table are estimates based on experience and are intended for use only as a guide."

This is on page 30 of my edition of Kodak Professional Data Book J-1, Processing Chemicals and Formulas for Black-and-White Photography

BTW Michael R., thank you for citing your source, guessing we have different editions as our page numbers differ.

It turns very brown and smells like sour rotten eggs over time... Then it is bad...

I guess I live way out there on the edge.
