CAS No.：148-79-8

Storage Temperature：20℃±4℃

Storage and handling The RM should be stored in the original sealed bottle at the temperatur given above.After use the bottle should be tightly closed and protected from moisture and light. The expirydate is valid for origimal sealed bottles under recommended storage conditions only.

Purity：98.89% （g/g）

Expanded Uncertainty U= 1.65% （g/g）

The uncertainty of this standard is alauiated in accordance with the IS0 Guide 34 and EURACHEM/CTAC Guide.Quantifying Uncertainty in Analytical Measurement, Second Edition. The expandeduncertainty 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 individualoperation involved in the analysis of the product： u（RM） =√u{char）²+ u（bb）²+ u（lts）²+ u（sts）²;u（char） is the uncertainty of purity determination; u（bb） uncertainty of homogeneity test; u（ts） uncertaintyof stability test long-term; ulsts）uncetainty of stability test short-term. U（[ts） and u（sts） are not induded in the calculation as the stability! sta tement is based on real evidence opposed to simulation.

Minimum sample： 1 mg is recommended as the minimal sample amount If less materialis used,it is recommended to increase the certified uncertainty by a factor of two for half sample and a factor offour for a quarter of sample.

Intended use： Use this RM as Calibrent for chromatography or any other analytical technique.
