Chemical Structure

Ammonium pentaborate tetrahydrate CAS 12046-04-7 chemical structure

Description

The molecular framework of Ammonium pentaborate tetrahydrate (B5O10H4NH2OH) is characterized by an inorganic composition. 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.

CATO supplies Ammonium pentaborate tetrahydrate (CAS 12046-04-7), a certified reference material (molecular formula B5O10H4NH2OH, MW 251.10 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ammonium pentaborate tetrahydrate 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.
