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 (Z)-[(4-Bromophenyl)[2-(4-chlorophenyl)cyclopropyl]methylidene]amino benzoate.
(Z)-[(4-Bromophenyl)[2-(4-chlorophenyl)cyclopropyl]methylidene]amino benzoate (CAS 338415-68-2), molecular formula C23H17BrClNO2 and molecular weight 454.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Z)-[(4-Bromophenyl)[2-(4-chlorophenyl)cyclopropyl]methylidene]amino benzoate (C23H17BrClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/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. 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), (Z)-[(4-Bromophenyl)[2-(4-chlorophenyl)cyclopropyl]methylidene]amino benzoate 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.
