Aluminium hydroxide

Catalog No.S4826 Synonyms: Aluminic hydroxide, Aluminum trihydroxide, Aluminium(III) hydroxide

For research use only.

Aluminium hydroxide (Aluminic), found in nature as the mineral gibbsite, is amphoteric (i.e., it has both basic and acidic properties). It is used to treat symptoms of increased stomach acid, such as heartburn, upset stomach, sour stomach, or acid indigestion; also reduce phosphate levels in people with certain kidney conditions.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
