Disodium 5'-inosinate

Disodium 5'-Inosinate, also known as IMP Disodium Salt, Disodium IMP, or Sodium Inosinate (FEMA 3669, CAS 4691-65-0), is a nucleotide salt derived from inosinic acid. It belongs to the Nucleosides and Nucleotides chemical category and is commercially referenced under the abbreviations IMP 2NA and Disodium IMP.

In food and nutrition applications, Disodium IMP functions as a flavour potentiator, synergising with glutamates to amplify umami taste at concentrations typically below 0.1%. In personal care formulations, it acts as a skin conditioner and protectant, contributing to moisture retention and barrier support through its interaction with cellular membrane components.

Disodium 5'-Inosinate is supplied as a crystalline powder meeting FCC and food-grade specifications, with compliance confirmed under REACH regulation. It is classified under HS code 29349990. Procurement teams should confirm grade suitability against FCC or internal quality standards prior to ordering.
