Chemical Structure

Dexmedetomidine Impurity 51 CAS 13651-55-3 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 Dexmedetomidine Impurity 51.

CATO supplies Dexmedetomidine Impurity 51 (CAS 13651-55-3), a pharmacopoeial impurity reference standard (molecular formula C9H11Cl, MW 154.64 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H11Cl, Dexmedetomidine Impurity 51 contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
