(7-Chloro-4,4-dioxido-1H-benzo[e][1,3,4]thiadiazin-3-yl)(morpholino)methanone CAS 1251703-64-6

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.

(7-Chloro-4,4-dioxido-1H-benzo[e][1,3,4]thiadiazin-3-yl)(morpholino)methanone (CAS 1251703-64-6), molecular formula C12H12ClN3O4S and molecular weight 329.76 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (7-Chloro-4,4-dioxido-1H-benzo[e][1,3,4]thiadiazin-3-yl)(morpholino)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
