(R)-2-(2,2-Dimethyl-1,3-dioxolan-4-yl)ethanol (R)-4-(2-Hydroxyethyl)-2,2-dimethyl-1,3-dioxolane 70005-89-9 H1188 CAS 70005-89-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-2-(2,2-Dimethyl-1,3-dioxolan-4-yl)ethanol (R)-4-(2-Hydroxyethyl)-2,2-dimethyl-1,3-dioxolane 70005-89-9 H1188.

(R)-2-(2,2-Dimethyl-1,3-dioxolan-4-yl)ethanol (R)-4-(2-Hydroxyethyl)-2,2-dimethyl-1,3-dioxolane 70005-89-9 H1188 (CAS 70005-89-9) is a high-purity analytical reference standard with the molecular formula C7H14O3 and a molecular weight of 146.18 g/mol.

Based on its molecular formula C7H14O3, (R)-2-(2,2-Dimethyl-1,3-dioxolan-4-yl)ethanol (R)-4-(2-Hydroxyethyl)-2,2-dimethyl-1,3-dioxolane 70005-89-9 H1188 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 146.18 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.
