FAQS on hypromellose cas number

Q: What is the CAS number for Hypromellose?

A: The primary CAS number for Hypromellose is 9004-65-3. It is a non-ionic cellulose ether widely used in pharmaceuticals and cosmetics.

Q: Is CAS 9002-89-5 associated with Hypromellose?

A: No, CAS 9002-89-5 corresponds to Polyvinyl Alcohol (PVA), not Hypromellose. Hypromellose has a distinct CAS number (9004-65-3).

Q: What is CAS 9004-32-4 used for?

A: CAS 9004-32-4 refers to Sodium Carboxymethyl Cellulose, a water-soluble polymer. It differs from Hypromellose in chemical structure and applications.

Q: How do I verify Hypromellose CAS number authenticity?

A: Check reputable chemical databases like PubChem or the CAS registry. Hypromellose is officially registered under 9004-65-3.

Q: Why are there multiple CAS numbers linked to Hypromellose?

A: Hypromellose variations may have different substitution grades, but the standard CAS is 9004-65-3. Other numbers like 9004-32-4 or 9002-89-5 refer to unrelated compounds.
