Chemical Structure
Description
N1-((1,4-Dioxaspiro[4.4]nonan-2-yl)methyl)-N2-(5-chloro-2-methylphenyl)oxalamide (CAS 899982-47-9), molecular formula C17H21ClN2O4 and molecular weight 352.81 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N1-((1,4-Dioxaspiro[4.4]nonan-2-yl)methyl)-N2-(5-chloro-2-methylphenyl)oxalamide (C17H21ClN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N1-((1,4-Dioxaspiro[4.4]nonan-2-yl)methyl)-N2-(5-chloro-2-methylphenyl)oxalamide 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.
