Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl (2Z)-3-(4-bromophenyl)-2-cyanoprop-2-enoate.
Methyl (2Z)-3-(4-bromophenyl)-2-cyanoprop-2-enoate (CAS 167995-88-2) is a high-purity analytical reference standard with the molecular formula C11H8BrNO2 and a molecular weight of 266.09 g/mol.
The molecular framework of Methyl (2Z)-3-(4-bromophenyl)-2-cyanoprop-2-enoate (C11H8BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
