Description
1264298-45-4 Triethylamine 3-((Z)-2-((E)-2-(2-(diphenylamino)-3-((E)-2-(5-methoxy-3-(3-sulfonatopropyl)benzo[d]thiazol-3-ium-2-yl)vinyl)cyclopent-2-en-1-ylidene)ethylidene) (CAS 1264298-45-4), molecular formula C43H43N3O8S4C6H15N and molecular weight 959.26 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, 1264298-45-4 Triethylamine 3-((Z)-2-((E)-2-(2-(diphenylamino)-3-((E)-2-(5-methoxy-3-(3-sulfonatopropyl)benzo[d]thiazol-3-ium-2-yl)vinyl)cyclopent-2-en-1-ylidene)ethylidene) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 959.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
