CAS No

28053-08-9

Appearance

White crystalline powder.

Purity

More than 98% (Moisture : approx. 7%)

Analytical methods

1. High performance liquid chromatography (HPLC)

Column	Shim-pack WAX-1 (4.0 mm ID x 50 mm)
Eluent	20 mM Phosphate buffer (pH 7.0) / 480 mM phosphate buffer (pH 6.85) gradient elution
Detection	260nm

2. Determination

The amount is calculated based on the molar extinction coefficient, ε₂₆₂ = 10,000, measuring the optical density at 262 nm in 0.01 N HCl solution (pH 2.0)

Storage

Stable when stored on desiccated condition at 5 ºC.
