Overview
The inositol described on this page is myo-inositol, a cyclitol with CAS 87-89-8. Rather than relying on the broad label “B-vitamin,” buyers should assess its chemical identity, stated purity, and physical quality. The assay must fall within 98.0–102.0%, while the specified melting point is 224–227°C.
The material must produce a solution as clear as distilled water and no darker in colour than the specified reference standards. This matters to buyers of powder beverages, liquid preblends, and clear formulations, for whom the appearance of the solution may matter as much as the nominal assay.
The specification limits each impurity to ≤0.3% and all impurities combined to ≤1.0%. It also sets very low limits for sulfate (≤0.006%) and chloride (≤0.005%). Along with a residue on ignition of ≤0.1%, these requirements distinguish a controlled, high-purity inositol grade from a general nutritional powder.
