Chemical Structure
Description
5-((2,4-Dichlorobenzyl)thio)-1,3,4-thiadiazol-2(3H)-imine (CAS 299933-96-3) is a high-purity analytical reference standard with the molecular formula C9H7Cl2N3S2 and a molecular weight of 292.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 5-((2,4-Dichlorobenzyl)thio)-1,3,4-thiadiazol-2(3H)-imine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.21 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).
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.
