(hydroxypropyl methylcellulose cas number)
Hydroxypropyl methylcellulose (CAS 9004-65-3) serves as a multifunctional polymer across pharmaceuticals, construction, and food production. This cellulose derivative shares regulatory significance with polyvinyl alcohol (CAS 9002-89-5), both requiring precise CAS identification for material safety documentation. Key characteristics include:
Modern HPMC formulations demonstrate 18% greater binding efficiency than standard ethylcellulose derivatives. Third-party testing confirms:
