Hydroxypropyl Methyl Cellulose CAS Number - Insights & Specs

Understanding Hydroxypropyl Methyl Cellulose CAS Number and Its Role

It’s funny how something as unassuming as a chemical hydroxypropyl methyl cellulose cas number can open a whole door into the world of industrial materials. If you’ve been around manufacturing or construction sites—especially the teams sorting out binders for cement or stabilizers for coatings—you’ve likely bumped into HPMC. I’ve been around these compounds for a long time, and frankly, this stuff feels like the Swiss Army knife of cellulose ethers.

So, what exactly does the CAS number do here? In real terms, that unique code (36483-46-56, for the record) is your passport to identifying hydroxypropyl methyl cellulose precisely among a sea of similar cellulose derivatives. It’s the shorthand a chemist or procurement specialist uses when quality, conformity, and traceability matter — and let’s be honest, in industrial supply chains, they always do.

Product Specifications at a Glance: Hydroxypropyl Methyl Cellulose

Specification	Typical Range	Notes
CAS Number	36483-46-56	Unique chemical identifier
Appearance	White to off-white powder	Highly water-soluble
Methoxy Content	19.0% – 24.0%	Affects viscosity and gelation
Hydroxypropyl Content	4.0% – 12.0%	Influences solubility and film-forming
Viscosity Range (2% solution)	20 – 4000 mPa.s	Wide grade variety for applications
PH (1% sol.)	5.0 – 8.0	Neutral to slightly alkaline

Every time I’ve had to vet HPMC for a project, these specs have saved the day — or at least prevented a late-night panic about a batch not forming the right gel or falling flat in viscosity. I recall a client once who insisted on using a lower-grade cellulose ether and ended up with a mortar that was way too runny. Lesson learned: don’t skimp when specs are at stake.

Choosing the Right Hydroxypropyl Methyl Cellulose Vendor: A Brief Comparison

Supplier	Grade Variety	Certifications	Lead Time	Pricing
SSH B HPMC	Extensive (20 – 4000 mPa.s)	ISO9001, REACH	2-3 weeks	Competitive
Supplier B	Moderate (50 – 2000 mPa.s)	ISO9001	3-4 weeks	Mid-range
Supplier C	Limited (100 – 1000 mPa.s)	None	1-2 weeks	Low

Honestly, the choice of supplier is often a balance between trustworthiness and cost. I usually lean toward suppliers who have proven reliability in certifications and stable delivery times — which explains why companies like SSH B HPMC are favored in my circles. It’s not just about the price tag; it’s about whether that powder will behave consistently, batch after batch.

Why the CAS Number Still Matters in Today’s Industrial Context

In an era where you can Google or scan a QR code to get product info, the CAS number remains a quiet workhorse. For anyone ordering HPMC — whether in construction, pharmaceuticals, or food industries — that number ensures you’re talking about the exact same molecule, regardless of packaging or branding. It’s been a subtle peacekeeper, honestly.

If you think about it, the CAS number is a bit like a vehicle’s VIN number. It might seem dull or tedious for the end user, but it’s the backbone of traceability, quality assurance, and compliance with global standards. Without it, you risk mix-ups that can cost time, money, and sometimes safety.

To wrap up... if you’re in the market for industrial binders or just curious about the building blocks behind your everyday products, understanding the importance of hydroxypropyl methyl cellulose and its CAS number is a practical starting point. And if you want a trusted supplier, the hydroxypropyl methyl cellulose cas number link I shared is a good doorway into reliable product info.

At the end of the day, materials might just look like powders or numbers on paper. But experience teaches you—the nuances matter. A lot.
