Final answer:
OTC derivative products offer the attractive feature of customization, allowing them to be tailored to specific financial needs, resulting in a flexible and accommodating market.

Unlike exchange-traded derivatives, OTC derivatives can be tailored in terms of the amount, duration, and the underlying asset, among other parameters. This customization creates a market that is more flexible and can accommodate a wider range of financial strategies and requirements. However, it is worth noting that the information provided seems to pertain to chemical processes and solvents like DMF and water in nucleotide synthesis, which does not relate to features of OTC derivative products in finance.
