Full Description

Piperazine (CAS 110-85-0) is a six-membered diamine heterocycle (C4H10N2) supplied for industrial synthesis and gas treating. It serves as a reactive amine in acid-gas scrubbing formulations, as a building block for corrosion inhibitors and surface-active agents, and as a curing amine and adhesive hardener.

Frequently Asked Questions

What is piperazine used for?

Piperazine (CAS 110-85-0) is a diamine heterocycle used industrially as a reactive amine activator in acid-gas scrubbing and CO2-capture formulations, as a building block for amine-based corrosion inhibitors and surface-active agents, as a curing agent for polychloroprene and similar elastomers, and as an adhesive hardener and chemical intermediate. RawSource supplies it for industrial synthesis and gas treating.

What is the chemical formula and structure of piperazine?

Piperazine is a six-membered ring diamine with formula C4H10N2 — two nitrogen atoms at opposite positions in a saturated ring. CAS is 110-85-0, HS code 2933.59.

Is piperazine an amine?

Yes. Piperazine is a cyclic secondary diamine, which is why it serves as a reactive amine in gas-treating, corrosion-inhibitor, and curing/hardener chemistries. Request a CoA for the assay of a given grade.

How is bulk piperazine shipped and classified?

Piperazine ships under UN 2579. RawSource supplies it with SDS and DOT documentation in drums and bulk; confirm form and packaging with your rep when requesting a quote.

What is the cost of bulk piperazine?

Bulk piperazine pricing depends on grade, form, packaging, and volume. RawSource quotes to spec — request a current bulk quote with your target quantity.
