Description

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.

2-Chloro-3-{[4-(dimethylamino)phenyl]amino}-1,4-dihydronaphthalene-1,4-dione (CAS 42262-96-4), molecular formula C18H15ClN2O2 and molecular weight 326.78 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Chloro-3-{[4-(dimethylamino)phenyl]amino}-1,4-dihydronaphthalene-1,4-dione (C18H15ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 326.78 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 2-Chloro-3-{[4-(dimethylamino)phenyl]amino}-1,4-dihydronaphthalene-1,4-dione 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.
