Infobox references

Trimethyllead chloride is an organolead compount with formula (CH3)3PbCl. It is a highly toxic colorless liquid.

Synthesis

Trimethyllead chloride can be synthesized by reacting tetramethyllead with hydrogen chloride.[3]

Pb(CH3)4 + HCl → (CH3)3PbCl + CH4

Uses

Trimethyllead chloride is primarily used in organic synthesis and as a reagent in various chemical reactions, particularly in the preparation of organolead compounds.[2]

Biochemistry

Trimethyllead chloride inhibits δ‐aminolevulinic acid dehydratase (ALAD) in vitro, although to a lesser extent than triethyllead chloride.[4]

Reactions

Trimethyllead chloride reacts with hexamethyldilead to yield tetramethyllead and lead(II) chloride.[5]

Hazards

As typical of organolead compounds, trimethyllead chloride is a poison. It is highly toxic to the environment, with long-lasting effects.[2]
