Chemical Structure

1,3-Dioxoisoindolin-2-yl 4-methylbenzenesulfonate CAS 56530-39-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dioxoisoindolin-2-yl 4-methylbenzenesulfonate.

1,3-Dioxoisoindolin-2-yl 4-methylbenzenesulfonate (CAS 56530-39-3) is a high-purity analytical reference standard with the molecular formula C15H11NO5S and a molecular weight of 317.32 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1,3-Dioxoisoindolin-2-yl 4-methylbenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.32 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).

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), 1,3-Dioxoisoindolin-2-yl 4-methylbenzenesulfonate 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.
