Description

Bialaphos CAS NO 35597-43-4 is a naturally occurring tripeptide herbicide and a potent glutamine synthetase inhibitor. This compound is a critical precursor for the production of the active herbicide phosphinothricin (glufosinate), making it a key intermediate in agrochemical manufacturing. It is primarily required by agrochemical producers, research institutions, and biotechnology companies for herbicide formulation, plant science research, and the development of transgenic, herbicide-resistant crops.

Application

• Agrochemical Intermediate: Primary use as a biosynthetic precursor for the commercial production of the non-selective herbicide glufosinate-ammonium.
• Herbicide Research & Development: Used in biochemical studies to investigate the mechanism of glutamine synthetase inhibition and its effects on plant physiology.
• Plant Biotechnology: Employed as a selective agent in the development and screening of transgenic plants engineered for herbicide resistance, particularly the bar or pat genes.
• Microbial Fermentation Studies: Serves as a substrate or reference standard in research involving Streptomyces hygroscopicus and other soil bacteria that produce bialaphos.
• Biochemical Reagent: Utilized as a high-purity standard in analytical laboratories for method development and quality control of herbicide formulations.

Quality Control

Our Bialaphos is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet the stringent requirements of research and industrial applications. A Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and purity.
