Not sure if this post belongs here or under general chemistry...
I found H2SO4 as a drain cleaner called "Clobber", I was told that it has an inhibitor so it doesn't corrode your piping system. Would this make it
useless as a reagent in conducting reactions?
Thanks!

We need to know what this "inhibitor" is. Its name is written on the label?

I unfortunately couldn't find it on either the label or the MSDS...here is a link to the MSDS, maybe someone will be able to interpret it better than
I.

Thanks!

Who told you about the "inhibitor"?
Based on the MSDS, this is a typical sulfuric acid drain cleaner. You can use it without worry.
If you need a more concentrated acid, read this.

If the inhibitor isn't toxic it doesn't have to be declaired on MSDS.
"Section 2 - Hazardous Ingredients/Identity Information"
I have found a few MSDS's that showed different components based on which country it was for. Same product, same brand, same manufacturer different
disclosure rules. Can't think of any off the top of my head, it was a while ago. When ever I hit up the hardware store ill snap pics of possibly
interesting products with my phone. Then look up the info online later so money isn't wasted on useless crap. Some times it pays to look at a ton of
different sites for the same info. Case in point:
http://www.oatey.com/doc/clobber.pdf
"Clobber is formulated with 93% virgin sulfuric acid concentrate and additives that inhibit corrosive action on ferrous and non-ferrous metals. In an
independent laboratory test*, Clobber was rated superior to similar type products in preventing corrosion. "
"Clobber may be used on cast iron, steel, copper, brass, lead and plastic pipe"
This wasn't from a European MSDS, but I found it looking for one

Thanks guys! This forum is proving to be very valuable I've been in contact with
my old chem teacher and he said it shouldn't be a problem.
I'll go head and pick some up. Where I work it'll cost me under $10 for 32oz 
And to answer the question of who told me; I called Hercules Chemical Company (Oatey) tech support and they told me that. However, it was a guy with
an extremely strong accent and I couldn't understand half of what he was saying -_-
