4-((1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-5-yl)oxy)phthalonitrile CAS 906673-33-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-5-yl)oxy)phthalonitrile.

CATO supplies 4-((1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-5-yl)oxy)phthalonitrile (CAS 906673-33-4), a certified reference material (molecular formula C15H9BN2O3, MW 276.05 g/mol) for analytical method development and quality control.

The molecular framework of 4-((1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-5-yl)oxy)phthalonitrile (C15H9BN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

As a certified reference material (CRM), 4-((1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-5-yl)oxy)phthalonitrile 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.
