TCI B6371 is bis(2,2,6,6-tetramethyl-3,5-heptanedionato)lead(II), CAS number 21319-43-7. It is a lead(II) coordination compound in which the metal centre is bound to two β-diketonate ligands. In the literature, compounds of this type are often abbreviated as Pb(TMHD)2 or Pb(thd)2. The material belongs to the inorganic chemistry and main-group element catalysis group. In the laboratory it serves as a source of lead that dissolves in organic solvents, so it is a good precursor for synthesising lead-based materials and for coordination chemistry studies.

Its bulky β-diketonate ligands carry tert-butyl groups. These give the complex a metal-organic character that sets it apart from ordinary inorganic lead salts, and they make it easier to handle in non-aqueous systems. For this reason, β-diketonate complexes are widely considered as precursors for thin-film coating techniques such as chemical vapour deposition (CVD) and atomic layer deposition (ALD). Researchers also choose this compound when they need a lead source with clearly defined stoichiometry, because each molecule contains exactly one lead centre and two identical ligands. For physical properties and the purity of a specific lot, refer to the product label and the manufacturer's data sheet.

In Indonesia, this material is most relevant to university chemistry and materials science departments, research institutes, and laboratories working on functional materials and thin films. Typical users are research groups that prepare lead-containing oxide or perovskite-type materials, study metal β-diketonate complexes, or test precursors for vapour-phase deposition. It also fits graduate thesis projects and research programmes in inorganic synthesis where a lead source compatible with organic solvents is needed. Labs usually order it in research quantities for controlled synthesis work rather than for routine analytical testing.

Store this compound in its original tightly closed container, in a cool, dry, well-ventilated area away from moisture, heat sources, and incompatible materials, unless the manufacturer's label says otherwise. Keep the container clearly labelled and separate from food and drink. Because this is a lead compound, handle it as a toxic substance. Wear gloves, safety glasses, and a lab coat, and weigh or transfer it in a fume hood to avoid breathing in dust or vapour. Wash your hands thoroughly after use. Collect waste and contaminated materials as heavy-metal hazardous waste according to local regulations. Always read the manufacturer's safety data sheet before use.
