5-methoxy-1,3-dimethyl-1H-pyrazole CAS 53091-80-8

Description

The occurrence of 5-methoxy-1,3-dimethyl-1H-pyrazole is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-methoxy-1,3-dimethyl-1H-pyrazole (CAS 53091-80-8), molecular formula C6H10N2O and molecular weight 126.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 5-methoxy-1,3-dimethyl-1H-pyrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-methoxy-1,3-dimethyl-1H-pyrazole 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.
