Chemical Structure

2-(Tert-butyl)-1,3-dioxoisoindoline-5-carboxylic acid CAS 57151-82-3 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.

2-(Tert-butyl)-1,3-dioxoisoindoline-5-carboxylic acid (CAS 57151-82-3), molecular formula C13H13NO4 and molecular weight 247.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Tert-butyl)-1,3-dioxoisoindoline-5-carboxylic acid (C13H13NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

As a certified reference material (CRM), 2-(Tert-butyl)-1,3-dioxoisoindoline-5-carboxylic acid 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.
