Chemical Structure

Fudosteine Impurity 45 CAS 1023971-15-4 chemical structure

Description

As a certified reference material (CRM), Fudosteine Impurity 45 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.

Fudosteine Impurity 45 (CAS 1023971-15-4) is a certified pharmaceutical impurity reference standard with the molecular formula C6H13NO3S and a molecular weight of 179.24 g/mol.

Structurally, Fudosteine Impurity 45 (C6H13NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 179.24 g/mol, it falls into the medium-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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
