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-[(1,1-dimethylethoxy)carbonyl](phenylmethyl)aminophenylboronic acid.
CATO supplies 4-[(1,1-dimethylethoxy)carbonyl](phenylmethyl)aminophenylboronic acid (CAS 693792-99-3), a certified reference material (molecular formula C18H22BNO4, MW 327.18 g/mol) for analytical method development and quality control.
The molecular framework of 4-[(1,1-dimethylethoxy)carbonyl](phenylmethyl)aminophenylboronic acid (C18H22BNO4) is characterized by a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-[(1,1-dimethylethoxy)carbonyl](phenylmethyl)aminophenylboronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
