Ractopamine hydrochloride
Formula：C18H23NO3 HCI
Mol. Welght：337.84
CAS No.：90274-24-1
Storage Temperature：20℃±4℃
Storage and handling：The RM should be stored in the original sealed bottle at the temperature given above.After use the bottle should be tightly closed and protected from moisture and light. The expiny date s valld for arlginal sealed bottles under recommended storage conddions only.
Purity：94.06% (g/g)
Expanded Uncertainty U=1.00% (g/g)
The uncertainty of this standard is calculated in accordance with the lSO Guide 34 and EURACHEM/CITAC Guide - Quantifying Uncertainty in Analytical Measurement, Second Edition.The expanded uncertainty is U(exp)=u(RM)x k, where k is the coverage factor at the 95% confidence level (k=2). Uncertainty u(RM)is based on the combination of the uncertainties associated with each indvidual operation involved in the analysis of the product u(RM)=vu(char)2+u(bb)2+u(lts)2+u(sts)2; u(char) is the uncertainty of charactersation; u(bb) uncertainty of homogeneity test;u(lts) uncertaintyof stability test long-term; u(sts) uncertainty of stablitytest short-term.u(lts) and u(sts) are not incuded in the calculation as the stablity statement is based on real evidence opposed to simulation.
Minimum sample: 1 mg is recommended as the minimal sample amount.If less material is used it is recommended to increase the ceritfied uncertainty by a factor of two for half sample and a factor of four for a quarter of sample.
Intended use: Use this RM as calibrant for chromatography or any other analytical technique.
