Product Identification

Article Code:DRE-C16540000 Article Name: Propyzamide
Formula: C12H11CI2NO 
Mol. Weight: 256.13 
CAS No.: 23950-58-5

Lot Number: G169356 
Expiry Date: 22.03.2024 
Storage Temperature: 20°℃ ± 4°℃

Storage and handling: The RM should be stored in the original sealed bottle at thetemperatur given above.After use the bottle should be tightly closed and protected from moisture and light The expiry date is valid for original sealed bottles under recommended storage conditions only.
 Purity: 99.14%(g/g) 
Expanded Uncertainty U= 0.32%(/g)
 The uncertainty of this standard is calculated in accordance with theiSO Guide 34 and EURACHEM/CITAC Guide-Quantifying Uncertainty in Analytical Measurement, Second Edition. The expanded uncertainty is U(exp)=u(RM)xk,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 individual operation involved in the analysis of the product:u(RM)=Vu(char)’+u(bb)’+u(ts)*+u(sts)*;u(char)is the uncertainty of purity determination; u(bb) uncertainty of homogeneity test; u(lts) uncertainty of stability test long-term;u(sts) uncertainty of stability test short-term.uits)andu(sts) are not included in the caiculation as the stability statement is based on real evidence opposed to simulation.
Minimum sample: 1 mg is recommended as the minimal sample amount.If less material is usedit is recommended to increase the certified 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
