The occurrence of 25135-51-7 Poly(oxy-1,4-phenylenesulfonyl-1,4-phenyleneoxy-1,4-phenylene(1-methylethylidene)-1,4-phenylene) Reigning NSC 170902 Polysulfone Polysulfone A Polysulphone UDEL Polysulfone P 1700 Reigning resin is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
25135-51-7 Poly(oxy-1,4-phenylenesulfonyl-1,4-phenyleneoxy-1,4-phenylene(1-methylethylidene)-1,4-phenylene) Reigning NSC 170902 Polysulfone Polysulfone A Polysulphone UDEL Polysulfone P 1700 Reigning resin (CAS 25135-51-7) is a high-purity analytical reference standard with the molecular formula C12H22O4SC15H28O2 and a molecular weight of 502.75 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 25135-51-7 Poly(oxy-1,4-phenylenesulfonyl-1,4-phenyleneoxy-1,4-phenylene(1-methylethylidene)-1,4-phenylene) Reigning NSC 170902 Polysulfone Polysulfone A Polysulphone UDEL Polysulfone P 1700 Reigning resin is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 502.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
