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.

Why is Inositol used in energy drinks and sports nutrition?

Inositol supports normal energy metabolism and fat metabolism, and it is often combined with taurine and caffeine in energy drinks. It is also used as a water-soluble nutrient in infant formula and general nutritional products.

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.

Inositol CAS 87-89-8

Inositol (CAS 87-89-8), specifically the myo-isomer, is a carbocyclic sugar naturally abundant in biological systems, functioning as a vital component of cell membranes and a secondary messenger in insulin signaling. Chemically identified as cis-1,2,3,5-trans-4,6-Cyclohexanehexol, this sweet-tasting white crystalline powder acts to support lipid metabolism and regulate cellular response to hormones. Historically classified as Vitamin B8, it is extensively integrated into infant formula (to support growth), functional beverages (often paired with Taurine), and aquaculture feed (to promote growth in fish and shrimp). In the pharmaceutical sector, it is a key ingredient in supplements for Polycystic Ovary Syndrome (PCOS) management due to its insulin-sensitizing effects. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific mesh sizes and purity standards (e.g., NF/FCC/Feed Grade). Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description

Inositol, specifically the Myo-Inositol isomer, is a carbocyclic sugar that is abundant in the brain and other mammalian tissues. It is a slightly sweet white powder (about half the sweetness of sucrose) and is water-soluble.

Why is it popular?

Energy Metabolism: It aids in the breakdown of fats and reduces blood cholesterol, making it a staple in “Energy Drinks” alongside Taurine and Caffeine.
Women’s Health: It is extensively used in supplements to support hormonal balance, particularly for Polycystic Ovary Syndrome (PCOS) management and insulin sensitivity.
Cell Growth: It acts as a growth factor for cells, which is why it is added to infant formula and high-quality animal feed (aquaculture).
