2-(3-Amino-1H-isoindol-1-ylidene)-2-cyano-N-methylacetamide CAS 87886-48-4

Description

The molecular framework of 2-(3-Amino-1H-isoindol-1-ylidene)-2-cyano-N-methylacetamide (C12H10N4O) 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.

2-(3-Amino-1H-isoindol-1-ylidene)-2-cyano-N-methylacetamide (CAS 87886-48-4), molecular formula C12H10N4O and molecular weight 226.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
