Chemical Structure
Description
Structurally, 2,2'-(Benzo[1,2-d:4,5-d']bis(thiazole)-2,6-diyl)diacetonitrile (C12H6N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 270.33 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.
2,2'-(Benzo[1,2-d:4,5-d']bis(thiazole)-2,6-diyl)diacetonitrile (CAS 1267681-21-9) is a high-purity analytical reference standard with the molecular formula C12H6N4S2 and a molecular weight of 270.33 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
