Authentic standard of TMA salt and β-alanine betaine ester detected by capillary electrophoresis. About 3.2 mM of β-alanine betaine and TMA were esterified with 4-bromophenacyl bromide as described in the ‘Methods’ section. The samples were injected hydrostatically (25 mm, 60 s) at 25°C. The applied potential was 20 kV, and the peaks were monitored at 262 nm.
