4,5,6,7-Tetrahydrothieno[3,2-c]pyridine CAS 54903-50-3

Description

Compared with other compounds in its class, the molecular weight of 139.22 g/mol gives 4,5,6,7-Tetrahydrothieno[3,2-c]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5,6,7-Tetrahydrothieno[3,2-c]pyridine (CAS 54903-50-3), molecular formula C7H9NS and molecular weight 139.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 4,5,6,7-Tetrahydrothieno[3,2-c]pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
