Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 287399-23-9 1-Bromo(4-~13~C)benzene DTXSID40736174.
287399-23-9 1-Bromo(4-~13~C)benzene DTXSID40736174 (CAS 287399-23-9) is a high-purity analytical reference standard with the molecular formula C5[13C]H10Br and a molecular weight of 163.04 g/mol.
287399-23-9 1-Bromo(4-~13~C)benzene DTXSID40736174 (C5[13C]H10Br) contains bromine substitution. Halogen substitution raises its density and boiling point; 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.
