5-Hydroxyisoindoline CAS 54544-67-1

Description

Compared with other compounds in its class, the molecular weight of 135.16 g/mol gives 5-Hydroxyisoindoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Hydroxyisoindoline (CAS 54544-67-1) is a high-purity analytical reference standard with the molecular formula C8H9NO and a molecular weight of 135.16 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Hydroxyisoindoline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 5-Hydroxyisoindoline 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.
