1-Benzyl-4-hydroxy-2-methyl-1H-benzimidazole-6-carboxylic acid(CAS: 1640981-19-6)

1-Benzyl-4-hydroxy-2-methyl-1H-benzimidazole-6-carboxylic acid is a white to off-white crystalline solid with a molecular weight of approximately 332.3 g/mol. It has a high solubility in organic solvents like methanol and ethanol but is poorly soluble in water. The compound is moderately reactive, particularly towards nucleophiles and reducing agents. It exhibits good absorption properties, which is beneficial for its use in sensor applications.

1-Benzyl-4-hydroxy-2-methyl-1H-benzimidazole-6-carboxylic acid is typically synthesized via a multi-step process involving the condensation of 2-methylbenzimidazole with benzylic alcohol, followed by the introduction of a hydroxyl group via a nucleophilic substitution reaction. The process requires careful control of reaction conditions to achieve high yields and selectivity.

1-Benzyl-4-hydroxy-2-methyl-1H-benzimidazole-6-carboxylic acid is used in various industries, including pharmaceuticals for its antioxidant and anti-inflammatory properties, polymers for its use as a stabilizer, and sensors for its ability to act as a chromogenic reagent. It is also of interest in the semiconductor industry as a dopant.

When handling 1-Benzyl-4-hydroxy-2-methyl-1H-benzimidazole-6-carboxylic acid, it is important to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. The compound should be used in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up immediately, and proper disposal procedures should be followed. Always consult the Safety Data Sheet (SDS) for detailed safety information.
