Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2S)-N,N inverted exclamation marka-Bis(2-acetyl-3-oxo-2-butenylidene)-1,2-dimesitylethylenediaminato cobalt(II) (S,S)-AMAC 259259-80-8.

(1S,2S)-N,N inverted exclamation marka-Bis(2-acetyl-3-oxo-2-butenylidene)-1,2-dimesitylethylenediaminato cobalt(II) (S,S)-AMAC 259259-80-8 (CAS 259259-80-8), molecular formula C32H50CoN2O4 and molecular weight 585.68 g/mol, is a CATO reference standard with documented purity and traceability.

(1S,2S)-N,N inverted exclamation marka-Bis(2-acetyl-3-oxo-2-butenylidene)-1,2-dimesitylethylenediaminato cobalt(II) (S,S)-AMAC 259259-80-8 (C32H50CoN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (1S,2S)-N,N inverted exclamation marka-Bis(2-acetyl-3-oxo-2-butenylidene)-1,2-dimesitylethylenediaminato cobalt(II) (S,S)-AMAC 259259-80-8 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.
