Description

4-Chlorobenzyl--D4 Cyanide is a deuterated organic compound, specifically a deuterium-labeled analog of 4-chlorobenzyl cyanide. This product matters for its utility as a stable isotope-labeled internal standard or a key synthetic intermediate in advanced research and development. It is primarily needed by professionals in pharmaceutical development, agrochemical research, and analytical chemistry for applications in mass spectrometry, metabolic studies, and the synthesis of novel chemical entities.

Application

• As a stable isotope-labeled internal standard for the precise quantification of its non-deuterated counterpart in bioanalytical methods using LC-MS/MS.
• A critical deuterated building block in the synthesis of more complex labeled pharmaceutical compounds for drug metabolism and pharmacokinetics (DMPK) studies.
• Used in agrochemical research for tracing the environmental fate and metabolic pathways of pesticides and herbicides.
• As a specialty intermediate in organic synthesis for creating deuterated liquid crystals or advanced materials.
• Employed in academic and industrial R&D for mechanistic studies and reaction pathway elucidation.

Quality Control

Our 4-Chlorobenzyl--D4 Cyanide is manufactured under strict quality systems to ensure high isotopic purity and chemical integrity. Each batch is characterized by advanced analytical techniques including NMR and Mass Spectrometry to confirm deuterium incorporation and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and identity is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in opaque secondary packaging.
