· KH2PO4

Potassium dihydrogen phosphate (KH₂PO₄) is an inorganic ceramic compound commonly classified as a phosphate salt with applications spanning optics, electronics, and specialty chemistry. It is primarily used in nonlinear optical devices, electro-optic modulators, and frequency-doubling crystals in laser systems, where its crystal structure enables efficient light manipulation. The material is also employed in fertilizer formulations, food additives, and as a buffering agent in laboratory and industrial processes, valued for its stability and low toxicity compared to alternative phosphate compounds.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
