BisphenolA (3-chloro-2-hydroxypropyl) glycidyl ether, ≥90% (HPLC), MilliporeSigma™ Supelco™
Bisphenol A (3-chloro-2-hydroxypropyl) glycidyl ether is a chlorinated derivative, which is released during the thermal coating treatment of food cans, big storage vessels and food containers.
VETRANAL™ Metronidazole, MilliporeSigma™ Supelco™
Chemical structure: imidazole
2,2-Dimethoxypropane, ≥99.4% (GC), MilliporeSigma™ Supelco™
2,2-Dimethoxypropane is an organic compound, which may be used as a protecting agent in the process of the synthesis of structurally related alkaloids like narciclasine and lycoricidine using phenylbromide as the starting material.
EPA TCL Pesticides Mix, Certified Reference Material, 2,000 μg/mL Each Component in Hexane: Toluene (1:1), MilliporeSigma™ Supelco™
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
Phenol-d6, Certified Reference Material, 2,000 μg/mL in Methylene Chloride, MilliporeSigma™ Supelco™
Phenol-d6 raw material is used to manufacturer this standard. However, phenolic hydrogen exchange occurs naturally, converting phenol-d6 to phenol-d5. In analyzing this standard, your chromatographic system will detect phenol-d5 rather tan phenol-d6.
Methimazole, ≥99%, MilliporeSigma™ Supelco™
Methimazole is an antithyroid agent, widely used in the treatment of hyperthyroidism.
phyproof™ Emodin 8-glucoside, ≥90% (HPLC), MilliporeSigma™ Supelco™
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG
Lithium Standard, For AAS, 1,000 mg/L Li in Nitric Acid, MilliporeSigma™ Supelco™
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034 (ISO Guide 34). This CRM is traceable to SI unit kg and measured against primary material from an NMI, e.g. NIST or BAM.
