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.

(5Z)-4-Chloro-N-(2-chloro-4-nitrophenyl)-5H-1,2,3-dithiazol-5-imine (CAS 303145-95-1) is a high-purity analytical reference standard with the molecular formula C8H3Cl2N3O2S2 and a molecular weight of 308.16 g/mol.

Structurally, (5Z)-4-Chloro-N-(2-chloro-4-nitrophenyl)-5H-1,2,3-dithiazol-5-imine (C8H3Cl2N3O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 308.16 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
