Description
CATO manufactures (9-Phenyl-9H-carbazol-4-yl)boronic 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.
(9-Phenyl-9H-carbazol-4-yl)boronic acid (CAS 1370555-65-9) is a high-purity analytical reference standard with the molecular formula C18H14BNO2 and a molecular weight of 287.12 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (9-Phenyl-9H-carbazol-4-yl)boronic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
