Chemical Structure
Description
The occurrence of 5-(Piperidin-4-yl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine dihydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Piperidin-4-yl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine dihydrochloride (CAS 1820650-25-6) is a high-purity analytical reference standard with the molecular formula C12H18N2SHCl and a molecular weight of 258.81 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 5-(Piperidin-4-yl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine dihydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
