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.
19339-58-3 CTK4E1237 Thiocyanic acid,2-(2-chlorophenyl)-2-oxoethyl ester (CAS 19339-58-3), molecular formula C9H6ClNOS and molecular weight 211.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 19339-58-3 CTK4E1237 Thiocyanic acid,2-(2-chlorophenyl)-2-oxoethyl ester (C9H6ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 19339-58-3 CTK4E1237 Thiocyanic acid,2-(2-chlorophenyl)-2-oxoethyl ester 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.
