Guanidine carbonate

Guanidine carbonate (CAS 593-85-1) is a stable salt form of guanidine.

Where is Guanidine carbonate used?

• Personal care: pH adjuster and active ingredient in hair products
• Hair straightening and relaxer products: reacts with hair proteins to alter structure
• Pharmaceutical and fine chemical synthesis: guanidylating agent and intermediate for antidiabetic and antimicrobial agents
• Polymer and resin production: catalyst or curing agent precursor in epoxy and melamine-based systems
• Food-grade formulations: buffering agent where alkaline pH control is required
• It serves as a preferred source of guanidine due to its controlled alkalinity and reactivity.

Good to know: Often selected where the free base or hydrochloride form is less practical to handle. Moisture-controlled packaging is standard given sensitivity to humidity and environmental factors during storage.

Commercial specifications

• Purity typically 98% to 99%+
• Packaging from small laboratory quantities to bulk industrial supply
