Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 25608-12-2 Polyacrylic acid, potassium salt Potassium polyacrylate 2-Propenoic acid, homopolymer, potassium salt Acrylic acid homopolymer potassium salt.
CATO supplies 25608-12-2 Polyacrylic acid, potassium salt Potassium polyacrylate 2-Propenoic acid, homopolymer, potassium salt Acrylic acid homopolymer potassium salt (CAS 25608-12-2), a certified reference material (molecular formula C3H4O2C3H3O2K, MW 182.22 g/mol) for analytical method development and quality control.
Structurally, 25608-12-2 Polyacrylic acid, potassium salt Potassium polyacrylate 2-Propenoic acid, homopolymer, potassium salt Acrylic acid homopolymer potassium salt (C3H4O2C3H3O2K) contains a carboxylic acid 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 182.22 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
