Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl (E)-3-(3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)-2-cyanoacrylate.
Methyl (E)-3-(3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)-2-cyanoacrylate (CAS 955964-55-3) is a high-purity analytical reference standard with the molecular formula C26H19N3O2 and a molecular weight of 405.45 g/mol.
The molecular framework of Methyl (E)-3-(3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)-2-cyanoacrylate (C26H19N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl (E)-3-(3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)-2-cyanoacrylate 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.
