· KBH4

KBH₄ (potassium borohydride) is an inorganic ceramic compound and strong reducing agent with ionic bonding characteristics. It is used primarily in chemical synthesis, metal processing, and pharmaceutical manufacturing as a versatile reducing agent and hydrogen source. Notable applications include metal hydride fuel cell development, specialty chemical production, and laboratory synthesis, where its reducing power and thermal stability make it valuable for processes requiring selective reduction or hydrogen generation.

Regulatory Screening

Environmental

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.
