Chemical Structure
Description
As a certified reference material (CRM), 2,3-Dimethyl-3'-(4-methylpiperazinomethyl) benzophenone 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.
2,3-Dimethyl-3'-(4-methylpiperazinomethyl) benzophenone (CAS 898788-70-0), molecular formula C21H26N2O and molecular weight 322.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3-Dimethyl-3'-(4-methylpiperazinomethyl) benzophenone (C21H26N2O) 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 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.
