(1-Ethyl-3-methyl-1H-pyrazol-5-yl)methanol CAS 1006464-74-9

Description

The occurrence of (1-Ethyl-3-methyl-1H-pyrazol-5-yl)methanol 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.

(1-Ethyl-3-methyl-1H-pyrazol-5-yl)methanol (CAS 1006464-74-9), molecular formula C7H12N2O and molecular weight 140.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, (1-Ethyl-3-methyl-1H-pyrazol-5-yl)methanol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.18 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.
