Chemical Structure

Acetaldehyde CAS 75-07-0 chemical structure

Description

CATO supplies Acetaldehyde (CAS 75-07-0), a certified reference material (molecular formula C2H4O, MW 44.05 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, Acetaldehyde is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 44.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
