3-(2-Mercapto-1H-imidazol-1-yl)thietane 1,1-dioxide CAS 1858892-10-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Mercapto-1H-imidazol-1-yl)thietane 1,1-dioxide.

3-(2-Mercapto-1H-imidazol-1-yl)thietane 1,1-dioxide (CAS 1858892-10-0), molecular formula C6H8N2O2S2 and molecular weight 204.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(2-Mercapto-1H-imidazol-1-yl)thietane 1,1-dioxide (C6H8N2O2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 204.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
