Chemical Structure

Ethyl 2-(3'-ethyl-4,4'-dioxo-2'-thioxo-3',4,4',5-tetrahydro-2'H,3H-[2,5'-bithiazolylidene]-3-yl)acetate CAS 1309456-13-0 chemical structure

Description

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.

Ethyl 2-(3'-ethyl-4,4'-dioxo-2'-thioxo-3',4,4',5-tetrahydro-2'H,3H-[2,5'-bithiazolylidene]-3-yl)acetate (CAS 1309456-13-0) is a high-purity analytical reference standard with the molecular formula C12H14N2O4S3 and a molecular weight of 346.45 g/mol.

Ethyl 2-(3'-ethyl-4,4'-dioxo-2'-thioxo-3',4,4',5-tetrahydro-2'H,3H-[2,5'-bithiazolylidene]-3-yl)acetate (C12H14N2O4S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

As a certified reference material (CRM), Ethyl 2-(3'-ethyl-4,4'-dioxo-2'-thioxo-3',4,4',5-tetrahydro-2'H,3H-[2,5'-bithiazolylidene]-3-yl)acetate 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.
