Chemical Structure
Description
As a certified reference material (CRM), 4-Methyl-N-[(Z)-1-(methylsulfanyl)-2-nitroethenyl]aniline 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.
4-Methyl-N-[(Z)-1-(methylsulfanyl)-2-nitroethenyl]aniline (CAS 142168-75-0), molecular formula C10H12N2O2S and molecular weight 224.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methyl-N-[(Z)-1-(methylsulfanyl)-2-nitroethenyl]aniline (C10H12N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
