Chemical Structure

(2R)-2-Methyl-butanoic Acid Ethyl Ester CAS 40917-00-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R)-2-Methyl-butanoic Acid Ethyl Ester.

(2R)-2-Methyl-butanoic Acid Ethyl Ester (CAS 40917-00-8), molecular formula C7H14O2 and molecular weight 130.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H14O2, (2R)-2-Methyl-butanoic Acid Ethyl Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 130.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
