Chemical Structure
Description
4-Isopropyl-3-methyl-2-(4-methylpiperazine-1-carbonyl)isoxazol-5(2H)-one (CAS 706804-15-1), molecular formula C13H21N3O3 and molecular weight 267.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Isopropyl-3-methyl-2-(4-methylpiperazine-1-carbonyl)isoxazol-5(2H)-one (C13H21N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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), 4-Isopropyl-3-methyl-2-(4-methylpiperazine-1-carbonyl)isoxazol-5(2H)-one 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.
