Chemical Structure

Pyrazolidin-3-one sulfate CAS 219312-95-5 chemical structure

Description

CATO supplies Pyrazolidin-3-one sulfate (CAS 219312-95-5), a certified reference material (molecular formula H2O4SC3H6N2O, MW 184.17 g/mol) for analytical method development and quality control.

The molecular framework of Pyrazolidin-3-one sulfate (H2O4SC3H6N2O) is characterized by an amide group, a sulfone group, a carboxylic acid 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.

As a certified reference material (CRM), Pyrazolidin-3-one sulfate 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.
