Guanidine acetate

Guanidine acetate (CAS 593-87-3, EC 209-814-2), also referred to as guanidinium acetate or guanidine monoacetate, is an organic salt formed from guanidine and acetic acid. It carries no assigned E-code and is commercially available as a white crystalline powder under several synonymous trade designations.

In pharmaceutical manufacturing, guanidine acetate serves as a pH buffer and stabilising agent in formulation processes where controlled ionic conditions are required. In agriculture and animal nutrition, it functions as a precursor to creatine biosynthesis, supporting metabolic energy pathways in feed applications. Its buffering capacity also finds use in food-grade processing where mild pH regulation is needed.

Guanidine acetate is sourced in pharmaceutical and feed grades, with supply subject to REACH registration requirements within the European market. Procurement professionals should confirm compliance with relevant pharmacopoeial standards where applicable. Standard packaging formats include fibre drums and multi-layer bags sized for industrial quantities.
