Chemical Structure
Description
The occurrence of 3-Chloro-2-({5-[(1E)-1-[(E)-2-[1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)ethylidene]hydrazin-1-ylidene]ethyl]thiophen-2-yl}methyl)-5-(trifluoromethyl)pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-2-({5-[(1E)-1-[(E)-2-[1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)ethylidene]hydrazin-1-ylidene]ethyl]thiophen-2-yl}methyl)-5-(trifluoromethyl)pyridine (CAS 321432-69-3) is a high-purity analytical reference standard with the molecular formula C26H18Cl2F6N4S2 and a molecular weight of 635.47 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 3-Chloro-2-({5-[(1E)-1-[(E)-2-[1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)ethylidene]hydrazin-1-ylidene]ethyl]thiophen-2-yl}methyl)-5-(trifluoromethyl)pyridine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 635.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
