Chemical Structure
Description
The occurrence of 3-Chloro-5,8-dimethyl-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-5,8-dimethyl-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide (CAS 1437434-06-4) is a high-purity analytical reference standard with the molecular formula C9H9ClN2O2S and a molecular weight of 244.70 g/mol.
Structurally, 3-Chloro-5,8-dimethyl-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide (C9H9ClN2O2S) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 244.70 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.
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.
