Chemical Structure

Dotinurad Impurity 96 CAS 861307-70-2 chemical structure

Description

Structurally, Dotinurad Impurity 96 (C7H7NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 153.20 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.

CATO supplies Dotinurad Impurity 96 (CAS 861307-70-2), a pharmacopoeial impurity reference standard (molecular formula C7H7NOS, MW 153.20 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Dotinurad Impurity 96 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.
