Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.75 g/mol gives Xylazole hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Xylazole hydrochloride (CAS 123941-49-1), molecular formula C11H12N2SHCl and molecular weight 240.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Xylazole hydrochloride (C11H12N2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
