2 Outline Introduction InsightMR Flow Tube InsightMR Software Setup Data Analysis with Dynamics Center

3 Reaction Monitoring What is it and Why are we Doing it? Reaction completion determination In-situ yield determination Reaction understanding: mechanistic information Extracting kinetic parameters Stability, degradation studies Dissolution Bio transformations Process control - PAT FDA providing guidelines for PAT

4 Techniques for Reaction Monitoring Calorimetry LC-UV MS, GC, GC-MS IR In-line (in-situ) measurements possible! NMR» At-line» In-line» On-line Quantitative by default: no need to calculate response factors! Information rich: possible to elucidate the structure of starting materials, products, and intermediates.

5 * Patent Pending What is InsightMR? Hardware Software InsightMR flow tube* InsightMR software package

6 InsightMR Flow Tube April 14, 2016

7 Concept InsightMR flow tube is an insert for virtually any Bruker 5 mm NMR probe. Enables online monitoring of chemical reactions in real-time under real conditions Fast and continuous transfer of reactions mixtures from a reaction vessel into the flow tube and back Continuously circulates the liquid from a reaction vessel through the NMR probe. The changing composition of the liquid in the vessel, i.e. the progress of the reaction, can be continuously monitored. Temperature control from the vessel to the probe and back achieved by running sample lines through temperature controlled heat transfer fluid

8 Basic Schematic InsightMR Package Customer Supplied NMR Magnet

9 Flow Tube Assembly Overview

10 Easy to Replace Flowcell Tube is easy to remove Cell protector doubles as an installation tool

11 Laboratory Setup Coventry, UK

12 Enabling parallel acquisition of data from different spectroscopies

13 Flow Behavior Delay of Transfer (a) Integral corresponds to 15 mm composition min Composition in pump was changed to 100% (c) After min change visible in NMR (d) After min 90% of target composition reached (e) After ~ min ~100% target composition reached (b) (e) (d) <1-2 min is possible by adjusting the flow rate to 2-3ml/min Adjustment of hardware (length diameter) also possible. (4 m length, 1 ml/min flow, 0.5 mm i.d. capillaries) (a) (c) Pump contributes ~100 ul to delay of concentration step propagation.
