Linaclotide impurity 38 CAS CATO-C4X-210638

Description

Compared with other compounds in its class, the molecular weight of 1553.86 g/mol gives Linaclotide impurity 38 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Linaclotide impurity 38 (CAS CATO-C4X-210638) is a certified pharmaceutical impurity reference standard with the molecular formula C64H84N10O21S7 and a molecular weight of 1553.86 g/mol.

Structurally, Linaclotide impurity 38 (C64H84N10O21S7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 1553.86 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Linaclotide impurity 38 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.
