Chemical Structure

Sulfobutylbetadex EP Impurity D CAS 61161-42-0 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 Sulfobutylbetadex EP Impurity D (CAS 61161-42-0), a pharmacopoeial impurity reference standard (molecular formula C8H18O7S2, MW 290.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Sulfobutylbetadex EP Impurity D (C8H18O7S2) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 290.35 g/mol, it falls into the medium-molecular-weight range.

As a certified reference material (CRM), Sulfobutylbetadex EP Impurity D 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.
