1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazin-5-one CAS 1384429-41-7

Description

The occurrence of 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazin-5-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazin-5-one (CAS 1384429-41-7), molecular formula C7H9N3O2 and molecular weight 167.17 g/mol, is a CATO reference standard with documented purity and traceability.

1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazin-5-one (C7H9N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazin-5-one 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.
