Chemical Structure
Description
As a certified reference material (CRM), N-methylthiophene-2-carbimidoyl chloride 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.
N-methylthiophene-2-carbimidoyl chloride (CAS 71267-32-8), molecular formula C6H6ClNS and molecular weight 159.64 g/mol, is a CATO reference standard with documented purity and traceability.
N-methylthiophene-2-carbimidoyl chloride (C6H6ClNS) contains a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
