Chemical Structure

(3-methyl-1H-pyrazol-4-yl)methanol CAS 51445-36-4 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, (3-methyl-1H-pyrazol-4-yl)methanol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 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.

(3-methyl-1H-pyrazol-4-yl)methanol (CAS 51445-36-4) is a high-purity analytical reference standard with the molecular formula C5H8N2O and a molecular weight of 112.13 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
