Why Preservative-Free Tafluprost 157283-68-6 Matters in 2025
Preservative-free Tafluprost (CAS 157283-68-6) has become the gold standard for sensitive glaucoma patients. Unlike benzalkonium chloride (BAK)-preserved alternatives, preservative-free formulations eliminate:
- Ocular surface damage (corneal toxicity in 58% of long-term users)
- Chronic inflammation leading to treatment discontinuation
- Allergic reactions in 12-30% of patients 8
With 2025 FDA guidelines prioritizing patient safety, demand for pure, additive-free prostaglandin analogs has surged 300% since 2022.
Critical Supplier Red Flags (Avoid These Risks!)
❌ Industrial-Grade Material Disguised as Pharma-Grade
Suppliers like Wuhan Dongkangyuan list “医药级” (medical-grade) but provide:
- No Certificates of Analysis (CoA)
- Zero stability data
- Null pricing indicating non-compliance 4
❌ Substandard Purity Claims
“Discount” vendors advertise ≥95% purity (e.g., TMstandard) but omit:
- Impurity profiles
- Residual solvent testing
- Heavy metal screening 3
❌ Counterfeit Cold Chain Protocols
Improper storage destroys efficacy:
- Tafluprost degrades at >-20°C
- Light exposure causes 40% potency loss in 48 hours 17
