Description
CATO supplies 2-(3-Chloro-2-methylpropyl)-5-ethylthiophene (CAS 1479323-17-5), a certified reference material (molecular formula C10H15ClS, MW 202.74 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Chloro-2-methylpropyl)-5-ethylthiophene (C10H15ClS) is characterized by sulfur-containing functionality, chlorine substitution. 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. 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.
As a certified reference material (CRM), 2-(3-Chloro-2-methylpropyl)-5-ethylthiophene 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.
