Description

General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Disodium inosinate is the disodium salt of inosinic acid which belongs to the group of purine-5′-nucleotides. It is generally used as a taste and flavor enhancer in foods to provide umami taste.

Application

Disodium inosinate may be used as a pharmaceutical reference standard for the determination of the analyte in raw materials and food products by spectrophotometry, and chromatography.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Inosine monophosphate, or inosinic acid, is the ribonucleotide of hypoxanthine and the first nucleotide formed during purine synthesis.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
