3,4-Bis(chloromethyl)-2,5-dimethylthiophene CAS 5368-70-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Bis(chloromethyl)-2,5-dimethylthiophene.

CATO supplies 3,4-Bis(chloromethyl)-2,5-dimethylthiophene (CAS 5368-70-7), a certified reference material (molecular formula C8H10Cl2S, MW 209.14 g/mol) for analytical method development and quality control.

Structurally, 3,4-Bis(chloromethyl)-2,5-dimethylthiophene (C8H10Cl2S) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 209.14 g/mol, it falls into the medium-molecular-weight range. 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).

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.

CATO manufactures 3,4-Bis(chloromethyl)-2,5-dimethylthiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
