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 2-Bromo-4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride.
2-Bromo-4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride (CAS 1956325-57-7) is a high-purity analytical reference standard with the molecular formula C7H8BrNSHCl and a molecular weight of 254.57 g/mol.
2-Bromo-4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride (C7H8BrNSHCl) contains a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
