Buffer solution, pH 4.0 ± 0.02 is used to establish and maintain an ion activity within narrow range. It is most commonly used to establish hydrogen-ion activity for the calibration of pH meters, in analytical procedures. It is also used to maintain stability of various dosage forms.
Chemically, the compound is represented by the formula C6H12O6 and could be found in plants and animals in huge quantities. Its common isomers include the L-glucose and D-glucose even though the fructose (i.e. which is the keto-form) is a widely established isomeric compound.
Thymol blue is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions. It transit from red to yellow at pH 1.2–2.8 and from yellow to blue at pH 8.0–9.6. It is usually a component of Universal indicator.
