Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Difluoromethoxy)piperidine oxalic acid.
3-(Difluoromethoxy)piperidine oxalic acid (CAS 1240528-92-0), molecular formula C6H11F2NOC2H2O4 and molecular weight 241.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(Difluoromethoxy)piperidine oxalic acid (C6H11F2NOC2H2O4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 3-(Difluoromethoxy)piperidine oxalic acid 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.
