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 23-Keto Nemadectin (Desmethoxyamino Moxidectin).
23-Keto Nemadectin (Desmethoxyamino Moxidectin) (CAS 112124-81-9), molecular formula C36H50O8 and molecular weight 610.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 23-Keto Nemadectin (Desmethoxyamino Moxidectin) (C36H50O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
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), 23-Keto Nemadectin (Desmethoxyamino Moxidectin) 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.
