Import Tips

• 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
