Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Propenoic acid, butyl ester, polymer with chloroethene.
2-Propenoic acid, butyl ester, polymer with chloroethene (CAS 25702-34-5), molecular formula C7H12O2C2H3Cl and molecular weight 190.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Propenoic acid, butyl ester, polymer with chloroethene (C7H12O2C2H3Cl) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 190.67 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
