BEC (99%), DDAB (98%), BAC12 (puriss, ≥99 %), BAC14 (puriss, ≥99 %), BAC16 (99%), hexadecyltrimethylammonium bromide (HDTAB, 99.5%) were purchased from Sigma-Aldrich (St. Louis, MO, USA). HDTAB was used as an internal standard (ISTD) for BEC and DDAB. Deuterated ISTDs (BAC12-d5, BAC14-d5, and BAC16-d5, 99%) were purchased from CDN Isotopes Inc. (Pointe Claire, Quebec). LCMS-grade acetonitrile, 2-propanol, formic acid, and ammonium formate were purchased from Thermo Scientific (Waltham, MA, USA). Water (18 MΩ) was cleaned by a Millipore Milli-Q system (Billerica, MA, USA). Polypropylene centrifuge tubes (15 ml) were purchased from Fisher Scientific. All samples and standards were passed through regenerated cellulose membrane filters (0.2-μm pore size, 15-mm i.d., Phenomenex, Torrance, CA, USA).
Regenerated cellulose membrane filters
Manufactured by Phenomenex
Sourced in United States
Regenerated cellulose membrane filters are designed for reliable and efficient filtration. They are made from high-quality regenerated cellulose material, providing consistent performance and durability. These filters are suitable for a variety of applications where precise filtration is required.

Regenerated cellulose membrane filters with 0.2 µm pore size and 4 mm diameter were purchased from Phenomenex. A Kinetex C18 column 100 mm × 2.1 mm, 2.6 µm column was purchased from Phenomenex, USA. The specific iron chelator SIH (salicylaldehyde isonicotinoyl hydrazone) was a kind donation from Professor Prem Ponka (McGill University, Montreal, QC, Canada). All other chemicals used were of analytical grade.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
