2,6-Dichloro-4-fluorobenzenethiol CAS 38366-83-5

Description

2,6-Dichloro-4-fluorobenzenethiol (CAS 38366-83-5), molecular formula C6H3Cl2FS and molecular weight 197.06 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,6-Dichloro-4-fluorobenzenethiol (C6H3Cl2FS) contains sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 197.06 g/mol, it falls into the medium-molecular-weight range. 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), 2,6-Dichloro-4-fluorobenzenethiol 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.
