Description

11-cis-3,4-Didehydro Retinal is a specialized, high-purity derivative of vitamin A (retinal) featuring a conjugated diene system at the 3,4-position in the 11-cis configuration. This compound is a critical chromophore precursor in the study of visual pigments and phototransduction pathways. It is primarily utilized by research institutions and pharmaceutical developers in the life sciences sector for advanced biochemical research, photobiology studies, and the synthesis of specialized retinoids.

Application

• Biochemical Research: Essential as a chromophore precursor for the study of rhodopsin and other visual pigment proteins in photobiology.
• Photochemistry Studies: Used to investigate the mechanisms of photoisomerization and the role of specific retinal isomers in vision.
• Pharmaceutical R&D: Serves as a key intermediate in the synthesis of novel retinoid-based therapeutics targeting retinal diseases.
• Reference Standard: Employed as a high-purity analytical standard in HPLC and LC-MS methods for quantifying retinoids in complex matrices.
• Nutraceutical Research: Investigated for its potential biological activity and metabolic pathways in advanced vitamin A research.

Quality Control

Our 11-cis-3,4-Didehydro Retinal is manufactured under strict quality control protocols to ensure high chemical purity and batch-to-batch consistency, suitable for sensitive research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. We adhere to relevant guidelines for research-grade chemicals, with specifications available to meet the stringent requirements of academic and pharmaceutical laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below to minimize oxidation and degradation. For long-term storage, keep the primary container sealed within a secondary, light-proof container. Allow the product to equilibrate to room temperature in a dry environment before opening to prevent condensation.
