Just wanted to ask about Phenidone, since more and more esoteric names for this has started to fly:
I have phenidone from Photograpic Formulary
Cat no 10-0870
CAS no 92-43-3
I have done some searching:
- Dimezone (4,4 Dimethyl 1 Phenyl 3 Pyrazolidone)
- Dimezone S (4 HydroxyMethyl 4 Methyl 1 Phenyl 3 Pyrazolidone)
- Phenidone A (1 Phenyl 3 Pyrazolidone)
- Phenidone B (4 Methyl 1 Phenyl Pyrazolidone)
Dimezone S is almost as active as the original
Phenidone but with lower level of fog.
?Name? Dimezone, Phenidone D
Phenidone-A : 162.19
Dimezone, or phenidone-D : 190.24
Dimezone-S : 206.24
To me it seems obvious it is very important to know what type of Phenidone one has, and adjust the recipes for this, if comparing notes shall serve any meaningful purpose at all.
