Chemical Structure

2-(Pyridin-3-yl)acetaldehyde CAS 42545-63-1 chemical structure

Description

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.

2-(Pyridin-3-yl)acetaldehyde (CAS 42545-63-1), molecular formula C7H7NO and molecular weight 121.14 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Pyridin-3-yl)acetaldehyde (C7H7NO) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
