Chemical Structure
Description
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.
CATO supplies Linaclotide Impurity 32 (CAS CATO-C4X-210632), a pharmacopoeial impurity reference standard (molecular formula C64H84N10O21S7, MW 1553.86 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Linaclotide Impurity 32 (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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
