3-Fluorobenzenethiol CAS 2557-77-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 3-Fluorobenzenethiol (CAS 2557-77-9), a certified reference material (molecular formula C6H5FS, MW 128.17 g/mol) for analytical method development and quality control.

Structurally, 3-Fluorobenzenethiol (C6H5FS) contains sulfur-containing functionality, fluorine 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 128.17 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 3-Fluorobenzenethiol 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.
