1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl spiro[2.3]hexane-1-carboxylate CAS 2248300-70-9

Description

As a certified reference material (CRM), 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl spiro[2.3]hexane-1-carboxylate 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.

1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl spiro[2.3]hexane-1-carboxylate (CAS 2248300-70-9), molecular formula C15H13NO4 and molecular weight 271.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl spiro[2.3]hexane-1-carboxylate (C15H13NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
