Chemical Structure

(R)-1-(1H-pyrazol-3-yl)ethan-1-ol hydrochloride CAS 1807939-22-5 chemical structure

Description

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

CATO supplies (R)-1-(1H-pyrazol-3-yl)ethan-1-ol hydrochloride (CAS 1807939-22-5), a certified reference material (molecular formula C5H8N2OHCl, MW 148.59 g/mol) for analytical method development and quality control.

Structurally, (R)-1-(1H-pyrazol-3-yl)ethan-1-ol hydrochloride (C5H8N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 148.59 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
