Description

Compared with other compounds in its class, the molecular weight of 198.07 g/mol gives Aluminum,hydroxy[1H-pyrazole-3,5-dicarboxylato(2-)-κO3]- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Aluminum,hydroxy[1H-pyrazole-3,5-dicarboxylato(2-)-κO3]- (CAS 2261060-23-3), a certified reference material (molecular formula C5H3AlN2O5, MW 198.07 g/mol) for analytical method development and quality control.

The molecular framework of Aluminum,hydroxy[1H-pyrazole-3,5-dicarboxylato(2-)-κO3]- (C5H3AlN2O5) is characterized by a carbohydrate-derived structure, an amide group. 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.

As a certified reference material (CRM), Aluminum,hydroxy[1H-pyrazole-3,5-dicarboxylato(2-)-κO3]- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
