Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Chlorophenyl)-4-isopropoxybutyronitrile.
4-(4-Chlorophenyl)-4-isopropoxybutyronitrile (CAS 6940-91-6) is a high-purity analytical reference standard with the molecular formula C18H23N3O10S3 and a molecular weight of 537.58 g/mol.
4-(4-Chlorophenyl)-4-isopropoxybutyronitrile (C18H23N3O10S3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-(4-Chlorophenyl)-4-isopropoxybutyronitrile 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.
