Chemical Structure
Description
The occurrence of Dasabuvir is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dasabuvir (CAS 1132935-63-7) is a high-purity analytical reference standard with the molecular formula C26H27N3O5S and a molecular weight of 493.57 g/mol.
Structurally, Dasabuvir (C26H27N3O5S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 493.57 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Dasabuvir meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
