About Famciclovir USP Related Compound C
Famciclovir USP Related Compound C is supplied as an analytical reference standard. It is registered under CAS number 174155-70-5.
The compound is characterised by its molecular formula C12H17N5O2 and a molecular weight of 263.30, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 263.1382 Da, a calculated LogP of 1.00, a topological polar surface area of 95.92 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: -20±5℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
