(E)-3-(2-(4-chlorophenyl)thiazol-5-yl)-3-oxopropanal O-methyl oxime CAS 339279-40-2

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.

(E)-3-(2-(4-chlorophenyl)thiazol-5-yl)-3-oxopropanal O-methyl oxime (CAS 339279-40-2) is a high-purity analytical reference standard with the molecular formula C13H11ClN2O2S and a molecular weight of 294.76 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (E)-3-(2-(4-chlorophenyl)thiazol-5-yl)-3-oxopropanal O-methyl oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), (E)-3-(2-(4-chlorophenyl)thiazol-5-yl)-3-oxopropanal O-methyl oxime 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.
