1H-Pyrazole-4-carboxylic acid, 1-(2-methoxyethyl)-, potassium salt (1:1) CAS 2095409-72-4

Description

Compared with other compounds in its class, the molecular weight of 208.26 g/mol gives 1H-Pyrazole-4-carboxylic acid, 1-(2-methoxyethyl)-, potassium salt (1:1) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1H-Pyrazole-4-carboxylic acid, 1-(2-methoxyethyl)-, potassium salt (1:1) (CAS 2095409-72-4), a certified reference material (molecular formula C7H9N2O3K, MW 208.26 g/mol) for analytical method development and quality control.

The molecular framework of 1H-Pyrazole-4-carboxylic acid, 1-(2-methoxyethyl)-, potassium salt (1:1) (C7H9N2O3K) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
