Application and regulatory boundary
A CAS record, website category or public literature mention does not establish performance in a pharmaceutical, polymer, coating, rubber, flavour, fragrance, cleaning or agricultural system. State the intended technical context, target transformation or formulation, quality standard and destination market so the required evidence can be reviewed.
Die WHO/JECFA No. 961 conclusion applies to the evaluated flavour use and then-current intake levels. It does not make a current Longchang lot food grade or universally permitted. Food and flavour projects require the current applicable specification, use level, destination-market rules and buyer approval.
Safety and handling boundary
This page is not a substitute for an SDS or a site-specific risk assessment. Request the current supplier SDS and use it with local rules and the buyer’s procedures to define classification, receipt, storage, transfer, processing, transport and disposal controls for the material supplied.
