1H-Pyrazolo[4,3-d]pyrimidine, 3-bromo-7-methoxy-1,5-dimethyl- CAS 1781698-05-2

Description

1H-Pyrazolo[4,3-d]pyrimidine, 3-bromo-7-methoxy-1,5-dimethyl- (C8H9BrN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1H-Pyrazolo[4,3-d]pyrimidine, 3-bromo-7-methoxy-1,5-dimethyl- (CAS 1781698-05-2), molecular formula C8H9BrN4O and molecular weight 257.09 g/mol, is a CATO reference standard with documented purity and traceability.

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), 1H-Pyrazolo[4,3-d]pyrimidine, 3-bromo-7-methoxy-1,5-dimethyl- 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.
