(4-Bromo-1-ethyl-1H-pyrazol-5-yl)methanol CAS 1310379-45-3

Description

The occurrence of (4-Bromo-1-ethyl-1H-pyrazol-5-yl)methanol is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Bromo-1-ethyl-1H-pyrazol-5-yl)methanol (CAS 1310379-45-3), molecular formula C6H9BrN2O and molecular weight 205.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-Bromo-1-ethyl-1H-pyrazol-5-yl)methanol (C6H9BrN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
