3-Methoxybutanal CAS 5281-76-5 chemical structure

Description

3-Methoxybutanal (CAS 5281-76-5), molecular formula C5H10O2 and molecular weight 102.13 g/mol, is a CATO reference standard with documented purity and traceability.

3-Methoxybutanal (C5H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
