Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Chloro-2-methyl-N-(thiophen-3-ylmethyl)aniline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-Chloro-2-methyl-N-(thiophen-3-ylmethyl)aniline (CAS 1040320-47-5), a certified reference material (molecular formula C12H12ClNS, MW 237.75 g/mol) for analytical method development and quality control.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
