5-Amino-3-(3,4-dichlorophenyl)-1H-pyrazole CAS 208519-10-2

Description

The occurrence of 5-Amino-3-(3,4-dichlorophenyl)-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Amino-3-(3,4-dichlorophenyl)-1H-pyrazole (CAS 208519-10-2), a certified reference material (molecular formula C9H7Cl2N3, MW 228.08 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Amino-3-(3,4-dichlorophenyl)-1H-pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.08 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.
