How DSIP is identified

Identity and purity are measured, not asserted. Electrospray mass spectrometry (ESI-MS) determines the mass-to-charge ratio of the intact molecule — an observed value matching the expected series above confirms the molecular formula. Reversed-phase HPLC separates the sample over time, and purity is read as arithmetic: the target peak’s area as a share of total peak area.

Frequently asked questions

What is DSIP?

What is the molecular formula of DSIP?

DSIP has the molecular formula C35H48N10O15, giving a molecular weight of 848.82 g/mol. Its monoisotopic mass is 848.3301 Da.

What is the CAS number of DSIP?

The CAS Registry Number for DSIP is 62568-57-4. Its InChIKey is ZRZROXNBKJAOKB-GFVHOAGBSA-N.

How is the identity of DSIP confirmed?

Identity is confirmed by electrospray mass spectrometry. The observed mass-to-charge ratio is compared against the expected series — for DSIP, [M+H]⁺ is expected at m/z 849.34. Purity is measured separately by reversed-phase HPLC as the target peak’s share of total peak area.

How should DSIP be stored?

DSIP is supplied as lyophilized powder and should be stored at 2–8 °C, desiccated. It is water-soluble.

Is DSIP a peptide?

Yes. DSIP is a peptide — a chain of amino-acid residues joined by peptide bonds, 9 residues in length. Its identity is defined by that sequence and its molecular mass.

Is DSIP approved for human use?

No. DSIP is supplied strictly for laboratory research use only. It is not a drug, is not approved by the FDA for any human or veterinary use, and must not be administered to humans or animals.
