Questions about this item:

Jose A  Is the same product used as polymerization inhibitor? CAS 123-31-9
ROBERT W  Jose A, Hydroquinone is primarily used as a developing agent in photography when producing B&W prints. It is known for enhancing contrast in the image. following is a quote from Ansel Adams book The Print, page 46: INGREDIENTS OF PRINT DEVELOPERS. 2. Hydroquinone. This is one of the first developing agents known. Hydroquinone has the property of enhancing contrast in the image by building up heavier deposits in the shadow areas of the print than could be obtained - in the same development time and from the same exposure - by the use of Metol alone. Hydroquinone and Metol in combination comprise the most popular and most universally used formulas. The formulas give thoroughly consistent results and have the advantages of long life and economy. Not clear how this would work in a chemical polymerization situation. Suggest you contact a chemical analyst.
Kevin A  Is this 100% pure Hydroquinone powder?
CHARLOTTE B  Yes, Its pure, but it was a crystalline powder not a true powder. And worked better for what i used it for. crystalline substances dissolve better than true powders
