Answer:The nominal molecular mass is approximately 35,000 g/mol, with a specified average range of about 28,000–38,000.
Answer:The CAS number is 25322-68-3.
Answer:The specified melting range is approximately 62–67°C.
Polyethylene glycol 35000 is used as a high-molecular-weight polymer reagent for chemical synthesis and materials-science workflows. The product is a polyethylene glycol/oxide material with CAS number 25322-68-3 and a nominal molecular mass of approximately 35,000 g/mol. The specified average molecular-mass range is about 28,000–38,000, and the material is stabilized with 2-tert-butyl-4-methoxyphenol. A 100 g/L aqueous solution has a specified pH of 5–7 at 20°C, and the melting range is approximately 62–67°C. The solid polymer can be used in synthetic formulations, polymer-processing studies, and laboratory methods that require a defined high-molecular-weight PEG rather than lower-mass liquid PEGs. The controlled molecular-mass and thermal specifications make it suitable for reproducible preparation of PEG-containing solutions and polymer formulations.
