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 (R)-Tetrahydrofuran-2-carbaldehyde.
(R)-Tetrahydrofuran-2-carbaldehyde (CAS 22170-11-2), molecular formula C5H8O2 and molecular weight 100.12 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-Tetrahydrofuran-2-carbaldehyde (C5H8O2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
