31212-13-2 2-Propenoic acid, potassium salt (1:1), polymer with 2-propenamide 2-Propenoic acid, potassium salt, polymer with 2-propenamide (CAS 31212-13-2), molecular formula C3H3KO2C3H5NO and molecular weight 181.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 31212-13-2 2-Propenoic acid, potassium salt (1:1), polymer with 2-propenamide 2-Propenoic acid, potassium salt, polymer with 2-propenamide (C3H3KO2C3H5NO) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 181.23 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
