(Z)-2-chloro-N-(5,5-dioxido-3-phenyltetrahydrothieno[3,4-d]thiazol-2(3H)-ylidene)acetamide CAS 951626-45-2

Description

(Z)-2-chloro-N-(5,5-dioxido-3-phenyltetrahydrothieno[3,4-d]thiazol-2(3H)-ylidene)acetamide (CAS 951626-45-2) is a high-purity analytical reference standard with the molecular formula C13H13ClN2O3S2 and a molecular weight of 344.84 g/mol.

Based on its molecular formula C13H13ClN2O3S2, (Z)-2-chloro-N-(5,5-dioxido-3-phenyltetrahydrothieno[3,4-d]thiazol-2(3H)-ylidene)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 344.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), (Z)-2-chloro-N-(5,5-dioxido-3-phenyltetrahydrothieno[3,4-d]thiazol-2(3H)-ylidene)acetamide 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.
