Mucic acid can be used to replace tartaric acid in self-rising flour or fizzies. It has been used as a precursor of adipic acid in the way to nylon by a rhenium-catalyzed deoxydehydration reaction. It has been used as a precursor of Taxol in Nicolaou Taxol total synthesis (1994).
Mucic acid, also called galactaric acid, is the dicarboxylic acid HOOC-(CHOH)4-COOH (C6H10O8). It forms when galactose, or a galactose-containing sugar such as lactose, is oxidised with nitric acid. It is a crystalline powder that is insoluble in alcohol, nearly insoluble in cold water, and melts at 210–230 °C. Although it has chiral carbons it is optically inactive, because the molecule is a meso compound.
That low solubility is what the mucic acid test relies on: a sugar sample is heated with nitric acid, and if galactose or lactose is present, insoluble crystals of mucic acid appear. Other uses: replacing tartaric acid in self-raising flour, and as a research precursor of adipic acid. For other carbohydrate reagents see periodic acid.

A test for galactose and lactose. Oxidation with nitric acid turns galactose into mucic acid, which separates as crystals because it hardly dissolves in cold water.
Galactose and compounds that contain it, such as lactose and many plant gums.
No. It is a meso compound: its two halves mirror each other, so it does not rotate polarised light.
Mucic acid test is a test that is highly specific and is used for the detection of the presence of galactose and lactose. It is also termed galactaric acid that is named after the product of the reaction.
MUCIC ACID Galactaric acid
Sugar acids obtained by aldohexose oxidation of both the terminal aldehyde group and the hydroxy group at the other end to carboxyl groups are called hexaric acids (i.e., six-carbon aldaric acids). Because hexaric acids have four secondary hydroxy groups that are stereochemically diverse and two carboxyl groups, various applications of these acids have been studied. Conventionally, hexaric acids have been produced mainly by nitric acid oxidation of aldohexose, but full-scale commercialization has not been realized; there are many problems regarding yield, safety, environmental burden, etc.
