Chemical Structure

2,2,3,3,3-Pentafluoropropane-1-thiol CAS 677-57-6 chemical structure

Description

The molecular framework of 2,2,3,3,3-Pentafluoropropane-1-thiol (C3H3F5S) is characterized by sulfur-containing functionality, fluorine 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.

2,2,3,3,3-Pentafluoropropane-1-thiol (CAS 677-57-6), molecular formula C3H3F5S and molecular weight 166.11 g/mol, is a CATO reference standard with documented purity and traceability.

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), 2,2,3,3,3-Pentafluoropropane-1-thiol 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.
