Chemical Structure
Description
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.
(T-4)-[N-[(Carboxy-κO)methyl]-N-methylglycinato(2-)-κN,κO](4-methylphenyl)boron (CAS 943552-01-0) is a high-purity analytical reference standard with the molecular formula C12H14BNO4 and a molecular weight of 247.05 g/mol.
The molecular framework of (T-4)-[N-[(Carboxy-κO)methyl]-N-methylglycinato(2-)-κN,κO](4-methylphenyl)boron (C12H14BNO4) is characterized by an amino-acid-derived structure, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures (T-4)-[N-[(Carboxy-κO)methyl]-N-methylglycinato(2-)-κN,κO](4-methylphenyl)boron 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.
