Chemical Structure
Description
The occurrence of (E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3-chlorobenzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3-chlorobenzoate (CAS 477872-44-9), a certified reference material (molecular formula C14H13ClN2O2S, MW 308.78 g/mol) for analytical method development and quality control.
(E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3-chlorobenzoate (C14H13ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), (E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3-chlorobenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
