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 7-(Piperazin-1-yl)thieno[2,3-c]pyridine hydrochloride.
7-(Piperazin-1-yl)thieno[2,3-c]pyridine hydrochloride (CAS 850734-85-9), molecular formula C10H10N2HCl and molecular weight 194.66 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10N2HCl, 7-(Piperazin-1-yl)thieno[2,3-c]pyridine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
