Which compound is ammonium biurate typically found in alkaline urine?

Alkaline urine promotes the formation of ammonium urate salts, so uric acid combines with ammonium under these conditions to form ammonium biurate crystals. These crystals are classically seen as yellow-brown, thorny-apple–like shapes in alkaline urine and are a hallmark of elevated urine pH, often due to urease-producing bacteria breaking down urea (for example, Proteus). So the compound you find associated with alkaline urine is ammonium biurate itself, reflecting the pH-driven crystallization of urate with ammonium.
