General Information

Rimegepant Impurities and Rimegepant  

Daicel Pharma is capable of synthesizing Rimegepant impurity standard, Rimegepant Sulfate and more. This impurity is essential for the quality, stability, safety, and efficiency analysis of Rimegepant. Furthermore, Daicel Pharma offers custom synthesis for Rimegepant synthesis for global delivery.

Rimegepant [CAS: 1289023-67-1] is an oral calcitonin gene-related peptide (CGRP) receptor antagonist for treating migraine headaches.

Rimegepant: Use and Commercial Availability 

Rimegepant treats and prevents migraine with or without aura in patients. It prevents episodic migraine attacks in adults. This drug is available under the brand name Nurtec ODT.

Rimegepant Structure and Mechanism of Action Rimegepant Structure and Mechanism of Action

The chemical name of Rimegepant is 4-(2,3-dihydro-2-oxo-1H-imidazo[4,5-b]pyridin-1-yl)- 1-Piperidinecarboxylic acid (5S,6S,9R)-5-amino-6-(2,3-difluorophenyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-9-yl ester. Its chemical formula is C28H28F2N6O3, and its molecular weight is approximately 534.6 g/mol.

Rimegepant prevents calcitonin gene-related peptide (CGRP) actions and treats migraine headache pain.

Rimegepant Impurities and Synthesis

Rimegepant, a medication for acute migraines, may contain impurities that arise during manufacturing1 or from degradation. These impurities are closely monitored and controlled to ensure product quality and safety. Manufacturers employ purification methods and conduct rigorous analytical testing to minimize impurity levels.

Daicel Pharma offers a Certificate of Analysis (CoA) for Rimegepant impurity standard, Rimegepant Sulfate. Our cGMP-certified analytical laboratory provides this CoA and includes detailed characterization data such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. More characterization details, such as those for 13C-DEPT, are provided on request. Daicel Pharma offers Rimegepant impurities and labeled compounds for testing the efficacy of generic Rimegepant. We can provide Rimegepant-D4, a deuterium-labeled Rimegepant standard, for bioanalytical research and Bioavailability/Bioequivalence (BA/BE) studies.


Frequently Asked Questions

Depending on the impurity and its concentration, purification techniques and methods can be employed to remove or reduce them in Rimegepant.

Regulatory authorities provide guidelines and limits for the level of impurities in pharmaceutical substances, including Rimegepant, to ensure product quality and safety.

The temperature conditions to control Rimegepant impurities typically involve storage and handling at specific temperature ranges, as specified in the drug's stability data and regulatory guidelines.

Rimegepant impurities should be stored at a controlled room temperature between 2-8°C or as indicated on the Certificate of Analysis (CoA).
