It has a role as an antimicrobial food preservative, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, a plant metabolite, a human xenobiotic metabolite, an algal metabolite and a drug allergen.It is a conjugate acid of a benzoate. m-2. The approximate solubilities of Pharmacopeial and National Formulary substances are indicated by the descriptive terms in the accompanying table. The term “miscible” as used in this Pharmacopeia pertains to a substance that yields a homogeneous mixture when mixed in any proportion with the designated solvent. Only where a special, quantitative solubility test is given in the individual monograph, and is designated by a test heading, is it a test for purity. This explanation is so stated under the subtitle: “, Description and Relative Solubility of USP and NF Moreover, an unexpected odor may be encountered if the characteristics of a substance are not known or if a container is incorrectly labeled. Description: - Very pale yellow to light tan-yellow, Odorless powder.
