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.
2579-22-8 Phenylpropynal Phenylpropiolaldehyde 3-Phenyl-2-propynal Propiolaldehyde, phenyl- (8CI) 2-Propynal, 3-phenyl- AI3-33277 Benzenepropiolaldehyde EINECS 219-942-0 NSC 47568 Phenylacetylenecarboxaldehyde Phenylpropargylaldehyde 3-Phenylpropynal (CAS 2579-22-8), molecular formula C9H12O and molecular weight 136.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2579-22-8 Phenylpropynal Phenylpropiolaldehyde 3-Phenyl-2-propynal Propiolaldehyde, phenyl- (8CI) 2-Propynal, 3-phenyl- AI3-33277 Benzenepropiolaldehyde EINECS 219-942-0 NSC 47568 Phenylacetylenecarboxaldehyde Phenylpropargylaldehyde 3-Phenylpropynal is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
