Chemical Structure

4-Fluoroisoindoline CAS 127168-78-9 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 4-Fluoroisoindoline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4-Fluoroisoindoline (CAS 127168-78-9) is a high-purity analytical reference standard with the molecular formula C8H8FN and a molecular weight of 137.15 g/mol.

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

As a certified reference material (CRM), 4-Fluoroisoindoline 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.
