Widely used as a source of formaldehyde in industrial and laboratory settings, it serves as a key reagent in the production of resins, particularly phenolic, urea-formaldehyde, and melamine-formaldehyde resins, which are essential in manufacturing plywood, particleboard, and laminates. It is also employed in disinfectants and fumigants due to its ability to release formaldehyde gas, making it effective for sterilizing equipment and facilities. In histology and pathology, it acts as a fixative for tissue samples, preserving cellular structure for microscopic examination. Additionally, it is used in the synthesis of pharmaceuticals, agrochemicals, and dyes, where controlled release of formaldehyde is required. Its solid form offers safer and more convenient handling compared to gaseous formaldehyde.
