Chemical Structure

3-(Methylthio)propionaldehyde CAS 3268-49-3 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 3-(Methylthio)propionaldehyde.

CATO supplies 3-(Methylthio)propionaldehyde (CAS 3268-49-3), a certified reference material (molecular formula C4H8OS, MW 104.17 g/mol) for analytical method development and quality control.

The molecular framework of 3-(Methylthio)propionaldehyde (C4H8OS) is characterized by sulfur-containing functionality, 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.
