ERG 2024 lists UN/NA 2045 (Isobutyl aldehyde) under Guide 130, titled “Flammable Liquids (Water-Immiscible/Noxious)”.
Material name
2045 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Isobutyl aldehyde” and “Isobutyraldehyde”. Both use Guide 130, so the number alone is enough to find the guide. On a numbered orange panel, 2045 is the lower number (how to read an orange panel).
ERG 2024 markings for 2045
2045 is not highlighted in green (no Table 1 entry), and its guide number 130 has no P.
