Chemical Structure

Propionic Acid-Ethyl Ester CAS 105-37-3 chemical structure

Description

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.

CATO supplies Propionic Acid-Ethyl Ester (CAS 105-37-3), a certified reference material (molecular formula C5H10O2, MW 102.13 g/mol) for analytical method development and quality control.

The molecular framework of Propionic Acid-Ethyl Ester (C5H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
