(RS)-1,1-Dimethoxy-2-propanol 2-Hydroxypropionaldehyde dimethyl acetal 42919-42-6 rac-Lactaldehyde dimethyl acetal CAS 42919-42-6

Description

The occurrence of (RS)-1,1-Dimethoxy-2-propanol 2-Hydroxypropionaldehyde dimethyl acetal 42919-42-6 rac-Lactaldehyde dimethyl acetal is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (RS)-1,1-Dimethoxy-2-propanol 2-Hydroxypropionaldehyde dimethyl acetal 42919-42-6 rac-Lactaldehyde dimethyl acetal (CAS 42919-42-6), a certified reference material (molecular formula C5H12O3, MW 120.15 g/mol) for analytical method development and quality control.

The molecular framework of (RS)-1,1-Dimethoxy-2-propanol 2-Hydroxypropionaldehyde dimethyl acetal 42919-42-6 rac-Lactaldehyde dimethyl acetal (C5H12O3) 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.

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.
