Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 191.19 g/mol gives 3-Benzotriazol-1-yl-propionic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Benzotriazol-1-yl-propionic Acid (CAS 654-15-9), a certified reference material (molecular formula C9H9N3O2, MW 191.19 g/mol) for analytical method development and quality control.
3-Benzotriazol-1-yl-propionic Acid (C9H9N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
