I'm new to searching this site so maybe I've missed it but beyond passing references to it I can't find much about gallic acid.
I'm looking for a UK supply of gallic acid. I've got pyrogallic acid (pyrogallol) but can't find the 'raw' acid.
Someone must have some info?

Fisher, ColeParmer, TCI - but as a private individual, perhaps eBay is a more sensible place to start.

Thanks, however, had a saved search on ebay for months - get loads of listings for health food supplements (none of which appear to even contain gallic acid), the odd vintage tin or label and a handbook costing over £200!
Importing from anywhere overseas is expensive - presumably because of 'hazard' restrictions and taxes.
CamLab in Cambridge list a solution in ethylene glycol of 8.5% and I've ordered a bottle to try. I'll come back with results (eventually) but would still like a supply of the dry powder.
The other companies you mention aren't interested in small quantities and/or selling to private individuals.

That's the biggest problem I face too whenever trying to source chemicals in the UK.

The auction site sometimes comes up trumps, but it'd be good to find a supplier who didn't restrict sales to schools or businesses.

And here's was me thinking that gallic acid was something that President Macron pours out occasionally when annoyed at "albion perfide"

May save you the hassle of collecting oak galls.

Don't think it hadn't crossed my mind.
However that's useful - don't know how I missed it - I thought I'd been through their list of chemicals.
Apparently gallic acid dissolves (in water) at between 1.19g per 100ml (anhydrous) and 1.5g per 100ml (monohydrate) at 20°C, which would mean that 500ml bottle contains around 6g dry powder; a bargain at the price they're asking.
On reflection I'd better buy at least one.
