Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[4-(8-Bromo-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile.
2-[4-(8-Bromo-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile (CAS 915019-53-3) is a high-purity analytical reference standard with the molecular formula C20H15BrN4O and a molecular weight of 407.26 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2-[4-(8-Bromo-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-[4-(8-Bromo-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
