Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Bis[(2-chloro-1,3-thiazol-5-yl)methyl]-1,4-diazepane.
1,4-Bis[(2-chloro-1,3-thiazol-5-yl)methyl]-1,4-diazepane (CAS 1208855-56-4) is a high-purity analytical reference standard with the molecular formula C13H16Cl2N4S2 and a molecular weight of 363.33 g/mol.
1,4-Bis[(2-chloro-1,3-thiazol-5-yl)methyl]-1,4-diazepane (C13H16Cl2N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. 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.
