Water System Sanitization & Control Standards

Sanitization of distribution system, including loop and storage tank is performed by Pasteurization. When Pasteurization sanitization is performed, the purified water in tank is heated up to 80°C and start to circulate by distribution system. The sanitization lasts 1 hour after reaching 80°C. Sanitization is performed every quarter. The purified water system sanitization logbook was checked with no excursion highlighted.

Frequently Asked Questions (FAQ)

Q1: What major applications are supported by these chemical products?
These compounds and peptide derivatives are primarily utilized for lysine side chain modifications and key peptide synthesis sequences including Semaglutide, Liraglutide, Albuvirtide, Insulin degludec, and various GLP-1 analogues.
Q2: What is the typical purity level guaranteed for these building blocks?
Most products maintain high purity standards ranging from ≥96.0% up to ≥99.5%, with strict controls on isomer content, specific impurities (SI), and moisture content (typically ≤1.0%).
Q3: What do the abbreviations "SI" and "Max" indicate in the specification chart?
"SI" refers to Specific Impurity limits, while "Max" represents the maximum allowable threshold for any single unknown impurity within the quality specification.
Q4: What general solvent residue limits apply across all these products?
Across all products listed, residual solvents are strictly controlled: Acetic Acid is capped at ≤0.02%, while Ethyl Acetate and Alcohol are each maintained at ≤0.5%.
Q5: How is purified water quality maintained during manufacturing?
The distribution loop and storage tanks undergo quarterly Pasteurization sanitization. Water is heated to 80°C and circulated continuously for 1 hour to ensure strict quality assurance with no system excursions.
Q6: Are specific intermediate fragments available for GLP-1 and Semaglutide manufacturing?
Yes, specialized intermediate fragments (such as Semaglutide Fragments A through G and Liraglutide Fragments 1 through 3) are provided with specified CAS numbers and strict quality indicators.
