Chemical Structure

Ent-Oseltamivir Phosphate CAS 1035895-89-6 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Ent-Oseltamivir Phosphate (CAS 1035895-89-6), molecular formula C16H28N2O4H3O4P and molecular weight 410.40 g/mol, is a CATO reference standard with documented purity and traceability.

Ent-Oseltamivir Phosphate (C16H28N2O4H3O4P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Ent-Oseltamivir Phosphate 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.
