Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-propenylacetate 3-pentenoic acid 5204-64-8 C5:1, n-2 CHEBI:38368 Pent-3-ensaeure beta-Aethyliden-propionsaeure beta-Butylen-alpha-carbonsaeure beta-penteic acid beta-pentenoic acid beta.gamma-Pentensaeure pent-3-enoic acid.
1-propenylacetate 3-pentenoic acid 5204-64-8 C5:1, n-2 CHEBI:38368 Pent-3-ensaeure beta-Aethyliden-propionsaeure beta-Butylen-alpha-carbonsaeure beta-penteic acid beta-pentenoic acid beta.gamma-Pentensaeure pent-3-enoic acid (CAS 5204-64-8), molecular formula C5H8O2 and molecular weight 100.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-propenylacetate 3-pentenoic acid 5204-64-8 C5:1, n-2 CHEBI:38368 Pent-3-ensaeure beta-Aethyliden-propionsaeure beta-Butylen-alpha-carbonsaeure beta-penteic acid beta-pentenoic acid beta.gamma-Pentensaeure pent-3-enoic acid (C5H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 100.12 g/mol, it falls into the low-molecular-weight range.
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.
