3-(Chloromethyl)-2-methylthiophene CAS 116608-03-8

Description

The occurrence of 3-(Chloromethyl)-2-methylthiophene is closely related to sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Chloromethyl)-2-methylthiophene (CAS 116608-03-8), molecular formula C6H7ClS and molecular weight 146.64 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(Chloromethyl)-2-methylthiophene (C6H7ClS) is characterized by sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
