Chemical Structure
Description
7-Ethoxy-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-one (CAS 137075-37-7) is a high-purity analytical reference standard with the molecular formula C13H13NO2 and a molecular weight of 215.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 7-Ethoxy-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 7-Ethoxy-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-one 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.
