2-Carboxybenzaldehyde
Based on 1 Customer Validation
2-Carboxybenzaldehyde (Phthalaldehydic acid) is a key intermediate metabolite in the biodegradation process of polycyclic aromatic hydrocarbons, and also a specific substrate for CBA reductase and NAD-dependent 2-carboxybenzaldehyde dehydrogenase. 2-Carboxybenzaldehyde undergoes regioselective reduction via CBA reductase in mammalian tissues to produce 2-hydroxymethylbenzoic acid. 2-Carboxybenzaldehyde is converted to phthalic acid by NAD-dependent dehydrogenase during bacterial degradation. 2-Carboxybenzaldehyde can be used in relevant research in fields such as organic synthesis.

Biological Activity
2-Carboxybenzaldehyde (CAB) (1 mM; 10 min at 37°C) is the preferred substrate of CBA reductase purified from the liver cytosol of phenobarbital-treated rats. It is converted to 2-hydroxymethylbenzoic acid in an NADH-dependent manner under the catalysis of CBA reductase. The apparent Km and Vmax values of this enzyme for 2-Carboxybenzaldehyde are 1.7 mM and 27.6 μmol/min per mg protein, respectively[1].
2-Carboxybenzaldehyde is specifically oxidized to phthalic acid by the purified NAD-linked dehydrogenase derived from Alcaligenes faecalis strain AFK2, with a Km value of 54 μM[2].
2-Carboxybenzaldehyde coordinates with Ca2+ ions to form an eight-coordinate monoclinic (space group C2/c) one-dimensional chain-like Ca2+ coordination polymer[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (16.65 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
