tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate

tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate may cause irritation to skin, eyes, or respiratory tract, or has low-level systemic toxicity. Adequate ventilation must be provided in work areas. Personal protective equipment (gloves, eye protection) is recommended during handling.

tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate is classified as a specific target organ toxicant (STOT). Exposure must be minimised using engineering controls (local exhaust ventilation, closed systems). Biological and medical monitoring may be required. Refer to the full Safety Data Sheet (SDS) Section 8 for occupational exposure limits.

tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate is hazardous to the aquatic environment. Do not allow this substance to enter drains, waterways, or soil. Spills must be contained immediately using appropriate absorbent material. Disposal must comply with local environmental regulations — consult the SDS Section 13 for guidance on waste treatment.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
