Chemical Structure

Isomalt Impurity 1 CAS CATO-C4X-33831 chemical structure

Description

As a process- or degradation-related impurity, Isomalt Impurity 1 (CAS CATO-C4X-33831, C12H22O11) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Isomalt Impurity 1 (C12H22O11) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 342.30 g/mol, it falls into the moderately-high-molecular-weight range.

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.

As a certified reference material (CRM), Isomalt Impurity 1 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.
