CAS No.：3844-45-9

Mol. Weight：792.85

Mol. Formula：C₃₇H₃₄N₂O₉S₃ . 2Na

Format：Neat

Storage Temp：20℃±4℃

Purity:82.0% (g/g)

Expanded Uncertainty U= 5.0% (g/g)

Uncertainty
The certified value(s) and uncertainty(ies) are determined in accordance with EURACHEM/CITAC Guide for "Quantifying Uncertainty in Analytical Measurement, 3rd edition", with an 95% confidence level (k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation and stability testing. Stability values are based on real evidence opposed to simulation.

The producer certifies that this reference material meets the specification stated in this certificate until the expiry date,provided it is stored unopened at the recommended temperature herein. Product warranties for this reference material areset out in the terms and conditions of purchase.

Method of Characterisation
Purity = 100% - Assay impurties - Water content (KF)

Method of ldentification
EA, NMR, RT, UV, IR

Batch Information
Water Content: 8.2% (g/g) by Karl- Fischer-Titration (U(exp) = 0.6% (g/g))
Main impurities are water and congeners.

Intended Use

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.

Safety

Proper precautions should be observed while handling. See Safety Data Sheet.

Traceability

The balances used for gravimetric measurements are calibrated with weights traceable to the national standards (DKD). The calibration ofthe balances is verified daily internally and annually by an external accredited calibration service. Chromatographic methods are traceable to the International System of Units (SI).

Homogeneity

Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with
ISO 17034.

Storage

The RM should be stored in the original sealed container at the indicated temperature.

Instructions for use

It is recommended to use 1 mg as theminimum sample size and if lessmaterial is used, to increase thecertified uncertainty by a factor of twofor half sample and four for a quarterof sample. If storage after opening is necessary, the RM should be tightlyclosed and kept from light andmoisture. If the RM was in a sealedampoule, it should be transferred to avial with minimum head space.
