What is Inositol CAS 87-89-8?

Inositol CAS 87-89-8 is a carbocyclic sugar with the molecular formula C6H12O6, EC number 201-781-2, and molecular weight 180.16 g/mol. Commercially, this CAS refers to myo-inositol, the most stable and biologically active stereoisomer in the inositol family.

What is the relationship between Inositol and Myo-Inositol?

Inositol is a general name for several stereoisomers, but in dietary supplements, pharmaceutical grades, and biological systems, CAS 87-89-8 normally means myo-inositol. Myo-inositol is the naturally abundant form found in the brain, cell membranes, and many foods.

How is myo-inositol used in women's health supplements?

Myo-inositol is commonly included in PCOS-support formulations because studies associate it with improved insulin sensitivity, hormone balance, and ovarian function. Doses in clinical studies are often around 2-4 g per day, but finished-product dosing should be confirmed for the intended formulation and population.

Why is Inositol added to aquatic feed?

Many fish and shrimp species require exogenous myo-inositol as a growth factor. Deficiency can lead to poor growth, reduced feed utilization, fin erosion, dark skin, and excess lipid accumulation in liver and muscle, so it is used as a standard aquaculture feed additive.
