  2. 분자량 정보 확인 부탁드립니다. 스펙 상에 분자량이 ~226.14 로 되어 있는데 실제 평균 분자량 값이 맞는지 궁금합니다. 문헌상에는 해당 물질의 분자량이 보통 수만 g/mol 로 되어 있어서 확인 드립니다.

    1 answer
    1. The molecular formula posted to the product page - (C12H22N2O2)n - is for the monomer. The subscript 'n' indicates that this product is a polymer. The molecular weight would vary by batch and has not been determined. According to other sources the molecular weight can range from 20,000 to 50,000 Daltons.
