How data was acquired |
DSC using a TA Instruments Q1000 equipped with a RCS unit. XRPD using a D8 Advance Bruker AXS diffractometer with a Cu radiation source at 40 kV and 35 mA. SEM using a JEOL JSM- 7001F/Oxford INCA Energy 250/HKL operated in high vacuum and 15 kV. |

Experimental factors |
For the DSC, the sample weighted between 5–10 mg and was analyzed in a pinholed aluminum pan. The heating ramp was from 25 °C to 250 °C at 10 °C/min. For the XRPD total scans, the samples were measured over a 2θ interval from 3° to 70° with a step size of 0.017° and step time of 50 s. For the XRPD slow scans, the 2θ interval was from 10° to 14° with a step size of 0.017° and step time of 1500 s. For the SEM analysis, the sample was attached to adhesive carbon tape, previously fixed to an aluminum stub. The sample were left under vacuum for 2 h and then coated with gold/palladium. |
Experimental features |
The DSC shown corresponds to the total heat flow. The diffractogram of the 1:1 Caffeine:Glutaric Acid cocrystal obtained from the Cambridge Software Database (form II – EXUQUJ) is also presented. SEM images correspond to 50× and 200× magnifications. |
