Chemical Structure
Description
The occurrence of 2,5-Diamino-3-chlorobenzonitrile is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Diamino-3-chlorobenzonitrile (CAS 82997-64-6), molecular formula C7H6ClN3 and molecular weight 167.60 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,5-Diamino-3-chlorobenzonitrile (C7H6ClN3) contains a nitrile group, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 167.60 g/mol, it falls into the medium-molecular-weight range. 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.
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.
