Use, compliance and safety boundary
The existing Longchang catalog classifies this material as a pharmaceutical intermediate. This classification does not establish pharmaceutical grade, approval, finished-product suitability or efficacy in a medical application. The buyer is responsible for evaluating the intended use and destination-market requirements.
Use the current supplier SDS and a site-specific risk assessment for handling, storage, transport and disposal. The legacy record says to store in a cool, ventilated warehouse, keep the container sealed and keep it away from fire and heat; confirm the current storage statement, shelf-life or retest information before ordering.
