Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.21 g/mol gives 5’-Inosinic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5’-Inosinic Acid (CAS 131-99-7), molecular formula C10H13N4O8P and molecular weight 348.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5’-Inosinic Acid (C10H13N4O8P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5’-Inosinic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
