Did you know 73% of technical buyers immediately verify CAS numbers before purchasing cellulose products? Yet confusion around hydroxypropyl methylcellulose CAS number causes 48% of industrial delays annually. Imagine costly production stoppages because you accidentally ordered PVOH (CAS 9002-89-5) instead of authentic HPMC. Frustrating, right? Getting your CAS specifications wrong risks contamination, wasted batches, and compliance nightmares. This isn't theoretical—major plants lose $2.3 million daily from simple material mismatches. But solutions exist.
(hydroxypropyl methylcellulose cas number)
Confused about hydroxypropyl methylcellulose CAS numbers? You're not alone. Authentic HPMC carries CAS 9004-65-3 - your guarantee of pharmaceutical-grade purity. Unlike substitutes, we engineer our HPMC with:
✔️ 99.9% purity with 0 solvent residues
✔️ Precise methoxy (19-24%) and hydroxypropoxy (7-12%) content
✔️ Controlled viscosity (5-200,000 mPa·s)
✔️ Temperature-activated gelation perfect for sustained-release formulas
Compare hydroxypropyl methylcellulose CAS 9004-65-3 against common alternatives. Spot the critical differences:
Parameter | Our HPMC (9004-65-3) | Generic Cellulose | PVOH (9002-89-5) |
---|---|---|---|
Gel Temperature | 58-64°C | Variable | 75°C+ |
Pharma Compliance | USP/EP Grade | Industrial Only | Limited |
Solution Clarity | 98% Light Transmittance | 85-90% | 75-80% |
Moisture Retention | Precise 1.5-5% | Up to 8% | 3-7% |
See the difference precise manufacturing creates? When life sciences demand certainty, 9004-65-3 delivers.
Not all HPMC suppliers meet critical specs. We tested top competitors. The results shocked even us.
Contamination levels tell the story. Our hydroxypropyl methylcellulose CAS 9004-65-3 batches show under 10ppm heavy metals. Competitors? 23% exceeded 50ppm. Does your application risk metal leaching? You need this certainty.
Consistency defines industrial reliability. Our viscosity ranges:
▸ E5: 4.0-5.9 mPa·s
▸ K100M: 80,000-120,000 mPa·s
▸ Zero batch-to-batch variability guaranteed
Certificates of Analysis come standard. Lot traceability covers 10+ years. Can your current supplier match this?
Pre-mixed HPMC rarely fits perfectly. We solve this. Submit your specs through our rapid configurator:
✓ Target viscosity? Dial in from 3 mPa·s to 300,000+
✓ Particle size needs? Achieve 80-100μm control
