It is often added to foods in conjunction with disodium guanylate; the combination is known as disodium 5'-ribonucleotides.; Disodium inosinate (E631), chemical formula C10H11N2Na2O8P, is the disodium salt of inosinic acid. It is a food additive often found in instant noodles, potato chips, and a variety of other snacks. It is used as a flavor enhancer, in synergy with monosodium glutamate (also known as MSG; the sodium salt of glutamic acid) to provide the umami taste. It is mainly found in animals like pigs and fish. 5'-Imp disodium salt 5'-IMP-Na2 5'-Inosinic acid, disodium salt 5'-Inosinic acid, sodium salt (1:2) Disodium 5'-inosinate disodium 5'-O-phosphonatoinosine Disodium 5'-ribonucleotide Disodium imp Disodium inosinate Disodium inosine 5'-monophosphate Disodium inosine 5'-phosphate Disodium inosine-5'-monophosphate E631 Imp disodium salt Imp sodium salt Inosin-5'-monophosphate disodium Inosine 5'-monophosphate disodium Inosine 5'-monophosphate disodium salt hydrate Inosine 5'IMP disodium salt Inosine-5'-monophosphate disodium Inosine-5'-monophosphate disodium salt octahydrate Inosine-5'-monophosphoric acid disodium salt Inosine-5'-phosphate Inosinic acid Ribotide Sodium 5'-inosinate Sodium inosinate C10H13N4O8P 348.206 348.047099924 {[3,4-dihydroxy-5-(6-hydroxy-9H-purin-9-yl)oxolan-2-yl]methoxy}phosphonic acid inosinic acid 4691-65-0 OC1C(COP(O)(O)=O)OC(C1O)N1C=NC2=C1N=CN=C2O InChI=1S/C10H13N4O8P/c15-6-4(1-21-23(18,19)20)22-10(7(6)16)14-3-13-5-8(14)11-2-12-9(5)17/h2-4,6-7,10,15-16H,1H2,(H,11,12,17)(H2,18,19,20) GRSZFWQUAKGDAV-UHFFFAOYSA-N belongs to the class of organic compounds known as purine ribonucleoside monophosphates.
