Import Tips & Compliance

Submit NMR or GC-MS spectra confirming isopropyl substitution to distinguish from excluded analogs

Package with stabilizer if prone to oxidation; declare as UN2785 for hazardous thiol transport

Verify not mixed with excluded isomers; pure compounds only qualify for this specific subheading
