Chemical Structure
Description
1-(1-(2-Ethyl-5-methoxy-4-nitrophenyl)piperidin-4-yl)-4-(methylsulfonyl)piperazine (CAS 1089282-90-5) is a high-purity analytical reference standard with the molecular formula C19H30N4O5S and a molecular weight of 426.53 g/mol.
The molecular framework of 1-(1-(2-Ethyl-5-methoxy-4-nitrophenyl)piperidin-4-yl)-4-(methylsulfonyl)piperazine (C19H30N4O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
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), 1-(1-(2-Ethyl-5-methoxy-4-nitrophenyl)piperidin-4-yl)-4-(methylsulfonyl)piperazine 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.
