Chemical Structure

(3-Nitro-1H-pyrazol-5-yl)methanol CAS 1000895-25-9 chemical structure

Description

The occurrence of (3-Nitro-1H-pyrazol-5-yl)methanol is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (3-Nitro-1H-pyrazol-5-yl)methanol (CAS 1000895-25-9), a certified reference material (molecular formula C4H5N3O3, MW 143.10 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (3-Nitro-1H-pyrazol-5-yl)methanol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.10 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.

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