Chemical Structure

(S)-(-)-α-Methylbenzyl Isocyanate CAS 14649-03-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 147.17 g/mol gives (S)-(-)-α-Methylbenzyl Isocyanate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-(-)-α-Methylbenzyl Isocyanate (CAS 14649-03-7) is a high-purity analytical reference standard with the molecular formula C9H9NO and a molecular weight of 147.17 g/mol.

Based on its molecular formula C9H9NO, (S)-(-)-α-Methylbenzyl Isocyanate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 147.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
