General description
Application
- In the synthesis of graphite oxide via electrochemical oxidation of natural graphite.
- As a reaction medium in oxidations reactions.
- As a dopant in the preparation of perchloric acid-functionalized polyaniline (HClO4/PANI) catalyst for the synthesis of 2-substituted benzothiazoles by condensation reaction between o-aminothiophenol with aldehydes.
It can also be used in the following:
- Silica-supported perchloric acid (HClO4-SiO2) is used as a catalyst to synthesize amidoalkyl naphthols by the condensation reaction of 2-naphthol, aromatic aldehydes, and acetonitrile.
- HClO4-SiO2 is used in the Friedlander quinoline synthesis by the condensation reaction of 2-aminoaryl ketones and carbonyl compounds.
- Alumina-supported perchloric acid (Al2O3-HClO4) is used as a catalyst in the synthesis of α-(α-amidobenzyl)-β-naphthols.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
