Chemical Structure
Description
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.
CATO supplies Methyl 4-[4-(3,4-dichlorobenzoyl)piperazin-1-yl]-3-nitrobenzoate (CAS 341967-75-7), a certified reference material (molecular formula C19H17Cl2N3O5, MW 438.26 g/mol) for analytical method development and quality control.
Methyl 4-[4-(3,4-dichlorobenzoyl)piperazin-1-yl]-3-nitrobenzoate (C19H17Cl2N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Methyl 4-[4-(3,4-dichlorobenzoyl)piperazin-1-yl]-3-nitrobenzoate 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.
