Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 325.36 g/mol gives Ethyl 5-benzyl-1,3-dimethyl-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 5-benzyl-1,3-dimethyl-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate (CAS 150582-34-6), a certified reference material (molecular formula C18H19N3O3, MW 325.36 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ethyl 5-benzyl-1,3-dimethyl-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 Ethyl 5-benzyl-1,3-dimethyl-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate 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.
