Quality Control

Our 1-Naphthoic Acid-D7 is manufactured under strict quality systems to ensure the high chemical purity and isotopic enrichment required for analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic purity (atom % D), chemical purity by HPLC, and identity confirmation. We adhere to relevant industry standards for reference materials, and custom specifications or GMP-grade material can be discussed to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability. For long-term storage, consider storing under an inert atmosphere.
