About Valsartan USP Related Compound E
Valsartan USP Related Compound E is supplied as an analytical reference standard. It is registered under CAS number 137863-17-3.
The compound is characterised by its molecular formula C25H31N5O3 and a molecular weight of 449.55, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 449.2427 Da, a calculated LogP of 4.25, a topological polar surface area of 101.07 Ų. It presents 1 hydrogen-bond donor and 6 acceptors. The structure carries 1 defined stereocentre, which is relevant wherever a stereochemically defined standard is required. These values are commonly used to anticipate chromatographic retention and to plan ionisation conditions during method development.
Each pack ships with a certificate of analysis reporting purity of 95%+ together with the supporting analytical data — HNMR, MS and HPLC or GC traces — so the material can be released straight into your own QC workflow. Recommended storage: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
