Butalbital or 5-allyl-5-isobutylbarbituric acid, is a derivative of barbituric acid which the hydrogens at position 5 are substituted by an allyl group and an isobutyl group. It is a short-to-intermediate acting member of barbiturates that exhibit muscle-relaxing and anti-anxiety properties that produce central nervous system (CNS) depression that ranges from mild sedation to general anesthesia. This product is designed for use in qualitative and quantitative protocols and can be used for forensic, toxicology, research, and other chemical/biochemical analytical applications.
