Chemical Structure
Description
The occurrence of N-(4-Bromo-3-methylphenyl)-2-[4-(3-chlorophenyl)piperazin-1-yl]acetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-Bromo-3-methylphenyl)-2-[4-(3-chlorophenyl)piperazin-1-yl]acetamide (CAS 329929-19-3) is a high-purity analytical reference standard with the molecular formula C19H21BrClN3O and a molecular weight of 422.75 g/mol.
The molecular framework of N-(4-Bromo-3-methylphenyl)-2-[4-(3-chlorophenyl)piperazin-1-yl]acetamide (C19H21BrClN3O) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), N-(4-Bromo-3-methylphenyl)-2-[4-(3-chlorophenyl)piperazin-1-yl]acetamide 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.
