3-Amino-1H-pyrazole-5-carbaldehyde CAS 1452554-33-4

Description

The occurrence of 3-Amino-1H-pyrazole-5-carbaldehyde 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.

CATO supplies 3-Amino-1H-pyrazole-5-carbaldehyde (CAS 1452554-33-4), a certified reference material (molecular formula C4H5N3O, MW 111.10 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Amino-1H-pyrazole-5-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 111.10 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.

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.
