Description

The occurrence of 2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-Terthiophene-5-boronic acid pinacol ester 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-terthiophene 849062-17-5 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-Terthiophene-5-boronic acid pinacol ester 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-terthiophene 849062-17-5 (CAS 849062-17-5), molecular formula C18H31BO2S3 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.

2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-Terthiophene-5-boronic acid pinacol ester 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2 inverted exclamation marka:5 inverted exclamation marka,2 inverted exclamation marka-terthiophene 849062-17-5 (C18H31BO2S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
