Chemical Structure
Description
The occurrence of (R)-8-Ethyl-4-methyl-2-phenyl-3,4,7,8-tetrahydro-5H-imidazo[2,1-i]purin-5-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (R)-8-Ethyl-4-methyl-2-phenyl-3,4,7,8-tetrahydro-5H-imidazo[2,1-i]purin-5-one (CAS 444717-56-0), a certified reference material (molecular formula C16H17N5OHCl, MW 331.80 g/mol) for analytical method development and quality control.
(R)-8-Ethyl-4-methyl-2-phenyl-3,4,7,8-tetrahydro-5H-imidazo[2,1-i]purin-5-one (C16H17N5OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures (R)-8-Ethyl-4-methyl-2-phenyl-3,4,7,8-tetrahydro-5H-imidazo[2,1-i]purin-5-one 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.
