3-Fluoro-4-methylbenzenethiol CAS 64359-35-9

Description

Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 3-Fluoro-4-methylbenzenethiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

3-Fluoro-4-methylbenzenethiol (CAS 64359-35-9), molecular formula C7H7FS and molecular weight 142.19 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), 3-Fluoro-4-methylbenzenethiol 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.
