Description

trans-Cinnamic-D7 Acid CAS NO 343338-31-8 is a high-purity, deuterium-labeled derivative of trans-cinnamic acid, where seven hydrogen atoms are replaced by deuterium. This isotopic labeling is critical for applications requiring precise internal standards in quantitative mass spectrometry, ensuring unmatched accuracy and reliability in analytical measurements. It is an essential material for researchers and quality control laboratories in the pharmaceutical, agrochemical, and advanced material science sectors, where metabolic pathway tracing and compound quantification are paramount.

Application

• Internal Standard for Quantitative Analysis: Serves as a critical deuterated internal standard in LC-MS and GC-MS for the accurate quantification of cinnamic acid and its derivatives in complex matrices.
• Pharmaceutical Research & Development: Used in pharmacokinetic (PK) and pharmacodynamic (PD) studies, drug metabolism and disposition (DMPK) research, and bioanalytical method development.
• Metabolic Pathway Tracing: Enables the study of phenylpropanoid and flavonoid biosynthesis pathways in plant biology and biochemistry through isotope tracing techniques.
• Agrochemical Analysis: Employed in the residue analysis and environmental fate studies of agrochemicals derived from or related to cinnamic acid structures.
• Food & Flavor Science: Acts as a stable isotope-labeled standard for the precise analysis of natural flavors, preservatives, and phenolic compounds in food products.
• Material Science Research: Utilized in the synthesis of deuterated monomers for producing labeled polymers with specific spectroscopic or physical properties.

Quality Control

Every batch of trans-Cinnamic-D7 Acid is manufactured and analyzed under strict quality management systems. We guarantee high chemical and isotopic purity, verified by advanced spectroscopic and chromatographic techniques including NMR, HPLC, and MS. A comprehensive Certificate of Analysis (COA) detailing assay, isotopic enrichment (D-enrichment), and impurity profile is provided with each shipment to ensure traceability and compliance with your research or quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
