tert-Butyl 3-chloro-7,7-dimethyl-6,7-dihydro-5H-pyrrolo[3,2-c]pyridazine-5-carboxylate CAS 1403901-53-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 283.75 g/mol gives tert-Butyl 3-chloro-7,7-dimethyl-6,7-dihydro-5H-pyrrolo[3,2-c]pyridazine-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl 3-chloro-7,7-dimethyl-6,7-dihydro-5H-pyrrolo[3,2-c]pyridazine-5-carboxylate (CAS 1403901-53-0) is a high-purity analytical reference standard with the molecular formula C13H18ClN3O2 and a molecular weight of 283.75 g/mol.

tert-Butyl 3-chloro-7,7-dimethyl-6,7-dihydro-5H-pyrrolo[3,2-c]pyridazine-5-carboxylate (C13H18ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), tert-Butyl 3-chloro-7,7-dimethyl-6,7-dihydro-5H-pyrrolo[3,2-c]pyridazine-5-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.
