Product Description of DL-Valine CAS#516-06-3
With the molecular formula C₅H₁₁NO₂ and molar-weight parameter 117.15, DL-Valine also goes under the aliases of DL-α-aminoisovaleric acid and DL-2-amino-3-methylbutyric acid. This amino-acid chemical presents itself as white crystalline powder. Its melting-point sits near 295 °C, and its boiling-point reaches 213.6 °C under standard 760 mmHg atmospheric pressure. The optical-rotation value falls within the scope -0.6°~+0.6° (test condition:20 °C/D, c=8, hydrochloric-acid solution). Being moisture-absorbent, DL-Valine possesses favourable solubility in aqueous liquid.
