Description

Compared with other compounds in its class, the molecular weight of 165.26 g/mol gives 2,5,6-Trimethyl-4H-thieno[3,2-b]pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5,6-Trimethyl-4H-thieno[3,2-b]pyrrole (CAS 830324-58-8), molecular formula C9H11NS and molecular weight 165.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5,6-Trimethyl-4H-thieno[3,2-b]pyrrole (C9H11NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 165.26 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.
