Urinary Trypsin Inhibitor CAS NO. 86449-31-6

In peptide-based formulation and bioassay development, sourcing a consistent and well-characterized inhibitor such as Urinary Trypsin Inhibitor is not just about its nominal identity - it's about predictable performance in analytical workflows, stability studies, and sterile handling environments. This material is provided as a pharmaceutical intermediate API, intended for integration into downstream processes rather than direct therapeutic use.

What You Receive With Each Batch

Documentation is designed for rapid integration into lab workflows and regulatory readiness:

• ▸ Certified Activity Profile: Batch-specific activity assays indicate inhibitor performance under defined conditions, enabling direct comparison with internal reference data.
• ▸ Purity & Impurity Data: HPLC/LC traces and impurity summaries allow QC teams to verify lot compliance without redundant testing.
• ▸ Safety & Handling Notes: MSDS and technical guidelines provide peptide API-specific instructions, including moisture and temperature sensitivity. This documentation set reduces the need for additional on-site characterization before use.

Critical Material Characteristics

• ▸ CAS Number: 86449-31-6
• ▸ Physical Form: White to off-white lyophilized powder
• ▸ Assay / Activity: Provided per lot in IU/mg or equivalent units
• ▸ Purity: Verified analytical data included
• ▸ Solubility Profile: Predictable in recommended buffer systems; see technical sheet for pH/solvent guidance
• ▸ Storage: Short-term 2–8 °C (sealed & dry); long-term −20 °C; protect from light and moisture

Practical Use Cases in Laboratory & Manufacturing

• ▸ Formulation Screening: Evaluate peptide interaction with buffers and excipients under sterile conditions.
• ▸ Analytical Method Validation: Use batch activity and impurity data to establish or confirm HPLC/LC assay performance.
• ▸ Stability Planning: Integrate COA data into internal models to project degradation and shelf-life behavior.

This approach ensures potential issues are identified early, minimizing surprises during pilot or production runs.

Handling & Integration Notes

• ▸ Aseptic Technique: Reconstitute and dilute using sterile procedures suitable for injectable or in-vitro assays.
• ▸ Moisture Sensitivity: Transfer only the required amount; reseal remaining powder promptly.
• ▸ Temperature Conditioning: Bring sealed vials to working temperature before opening to prevent condensation.

Packaging & Logistics

• ▸ Primary Packaging: Moisture-barrier vials with desiccant, suitable for cold chain or dry shipment.
• ▸ Shipping Options: Temperature-controlled transport available for clients in hot climates.
• ▸ Label Clarity: Batch number and activity labeling designed for easy integration into LIMS or ERP systems.

Procurement & Evaluation Workflow

• ▸ Initial Assessment: Sample orders for solubility, activity, and impurity verification.
• ▸ Internal Qualification: QC and formulation teams review COA, MSDS, and stability data against internal standards.
• ▸ Scale-Up Ordering: Transition to bulk supply with confirmed performance and scheduled delivery.
