Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Tetrahydro-2H-pyran-2-yl)acetaldehyde (CAS 86266-57-1), molecular formula C7H12O2 and molecular weight 128.17 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Tetrahydro-2H-pyran-2-yl)acetaldehyde (C7H12O2) 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.
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.
