Chemical Structure
Description
The occurrence of 4-Ethyl-1,6,7,8-tetrahydro-10H-pyrano[3,4-f]indolizine-3,10(4H)-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Ethyl-1,6,7,8-tetrahydro-10H-pyrano[3,4-f]indolizine-3,10(4H)-dione (CAS 43083-10-9), molecular formula C13H15NO3 and molecular weight 233.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Ethyl-1,6,7,8-tetrahydro-10H-pyrano[3,4-f]indolizine-3,10(4H)-dione (C13H15NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Ethyl-1,6,7,8-tetrahydro-10H-pyrano[3,4-f]indolizine-3,10(4H)-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
