Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(2,5-Difluorophenyl)-1,4-thiazepane hydrochloride.
7-(2,5-Difluorophenyl)-1,4-thiazepane hydrochloride (CAS 2097936-26-8), molecular formula C11H13F2NSHCl and molecular weight 265.75 g/mol, is a CATO reference standard with documented purity and traceability.
7-(2,5-Difluorophenyl)-1,4-thiazepane hydrochloride (C11H13F2NSHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
