Chemical Structure
Description
Structurally, 3,5-Dichloro-1,2-diaminobenzene 3,5-Dichloro-1,2-phenylenediamine 5233-04-5 (C6H12Cl2N2) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 183.08 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3,5-Dichloro-1,2-diaminobenzene 3,5-Dichloro-1,2-phenylenediamine 5233-04-5 (CAS 5233-04-5) is a high-purity analytical reference standard with the molecular formula C6H12Cl2N2 and a molecular weight of 183.08 g/mol.
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.
