Phloroglucin 1%, alcoholic, is a staining solution mainly used in histology and botany. Phloroglucin is a phenolic derivative that serves as a staining reagent for selective staining of lignin, an important structural component in lignified plant tissues.

In a 1% alcoholic solution, phloroglucin is highly soluble and can effectively penetrate tissue samples. The alcoholic solution enables faster and more uniform staining of lignin structures. Phloroglucin stains are commonly used in plant histology to visualize cell walls and lignified structures such as xylem and sclerenchyma.

Phloroglucin reacts with lignin to form a red dye complex that is readily visible under the microscope. The stain is particularly useful in the study of wood and plant structures to visualize the distribution and organization of lignin in tissues.

The 1% alcoholic phloroglucin solution is specifically designed for professional use in histological and botanical laboratories and provides a reliable and efficient method for staining lignin in tissue sections and plant preparations.
