General description

Cholesteryl benzoate (CB) is a cholesteryl ester which is used in cholesteric liquid crystals by forming layered spiral staircases in which the rotation angle is temperature dependent.

Application

Cholesteryl benzoate (CB) is a structure directing agent which can be used in the growth of oriented lithium iron phosphate (LiFePO₄) for the fabrication of lithium ion batteries. It can be used in the fabrication of polymer dispersed liquid crystals (PDLC) which show liquid crystallinity by cooling the material from the isotropic phase.

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.
