3-(Benzo[d][1,3]dioxol-5-yl)isoxazole-4-carbonitrile (CAS 55836-73-2) is a high-purity analytical reference standard with the molecular formula C7H13D2Cl2N2O2P and a molecular weight of 263.10 g/mol.
The molecular framework of 3-(Benzo[d][1,3]dioxol-5-yl)isoxazole-4-carbonitrile (C7H13D2Cl2N2O2P) is characterized by deuterium isotope labeling, an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 3-(Benzo[d][1,3]dioxol-5-yl)isoxazole-4-carbonitrile 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.
